Introduction

A linked list is a collection of values or objects with the following rules:

• Each item in the list is called a node (this is not an actual rule but a habit or a suggestion)

• If the list is empty, it may have one item referred to as null
• If the list was just empty, when a new node is added, that node becomes the first and last item
• If the list has only one node, that node represents the first and the last item

• If the list contains at least one node, whenever a new node is added, that new node is positioned as the last in the list. This is because the new node is added next to the existing node
• If the list contains more than one node, each item holds a reference to the object next to it

In reality, there are various types of linked lists. A singly linked list is a one-way directional list where each item points (only) to the item next to it (in a somewhat right direction). The description we just gave is conform to a singly linked list. Another type is the doubly linked list:

• Each item in the list is called a node (again, this is not a real rule)
• If the list is empty, it may have one item referred to as null or two items referred to as nulls
• If a new node is added to an empty list, that node is added as the first in the collection
• If the list contains one node, that node has two references to itself: one reference as the next and the other reference as its previous
• If the list contains two nodes:
• One node is the first. That first node holds a reference to the other node as its next
• The other node is the last. That last node holds a reference to the first node as its previous item
• If the list contains more than two nodes:
• The first node holds a reference to the next node (in the right direction)
• The last node holds a reference to the node previous to it (in the left direction)
• Each node holds two references: one reference to the previous node and one reference to the next node

The last type of linked list is called a circular linked list. This list is primarily created as either a singly linked list or a doubly linked list:

• In a circular singly linked list, the list primarily follows the rules of a singly linked list. then:
• If the list has two nodes, the first node holds a reference to the other node as its next and its previous node
• If the list has more than one node:
• The first node holds a reference to the last node as its previous object
• The last node holds a reference to first node as its next

• In a doubly linked list, the list includes the rules of the doubly linked list and combines with those of the circular singly linked list:
• The first node has a reference to the last node as its previous node
• The last node has a reference to the first node as its next node
• Each node has two references: its previous and its next nodes

{
return base.GetHashCode();
}
}
}```
26. In the middle list of the Add Scaffold dilaog box, click MVC 5 Controller With Read/Write Actions
28. Type ViolationsTypes to get ViolationsTypesController

Although you can create a linked list collection class from scratch, to assist you, the .NET Framework provides a class named LinkedList that is a member of the System.Collections.Generic namespace. LinkedList is a generic collection class with three constructors. The default constructor allows you to create an empty linked list. IfHere is an example of using it:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Fundamentals.Controllers
{
public class ExerciseController : Controller
{
public ActionResult Exercise()
{

return View();
}
}
}
}
}```

Of course you can also declare a LinkedList variable in a view. Here is an example:

```@{
ViewBag.Title = "Exercise";
}

<h2>Exercise</h2>

@{
}```

Another constructor allows you to create a linked using an existing list. Its syntax is:

`public LinkedList(IEnumerable<T> collection);`

The argument can be a variable from any class that implements the IEnumerable<T> interface. Here is an example of using this second constructor:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Exercise01()
{
List<double> values = new List<double>();

return View();
}
}
}```

Practical Learning Creating a Linked List

1. Change the document as follows:
```using System.IO;
using System.Web.Mvc;
using System.Collections.Generic;
using TrafficTicketsSystem1.Models;
using System.Runtime.Serialization.Formatters.Binary;

namespace TrafficTicketsSystem1.Controllers
{
public class ViolationsTypesController : Controller
{
// GET: ViolationsTypes
public ActionResult Index()
{
FileStream fsViolationsTypes = null;
BinaryFormatter bfViolationsTypes = new BinaryFormatter();
string strViolationsTypesFile = Server.MapPath("~/App_Data/ViolationsTypes.tts");

// If a file for violations types was proviously created, open it
if (System.IO.File.Exists(strViolationsTypesFile))
{
{
/* After opening the file, get the list of records from it
* and store in the declared LinkedList<> variable. */
}
}

return View(categories);
}

. . .
}
}```
2. In the Solution Explorer, right-click Controllers -> Add -> New Scaffolded Item...
3. In the left list of the Add Scaffold dialog box, click MVC and, in the middle list, click MVC 5 Controller With Read/Write Actions
5. Type Cameras to get CamerasController
7. Change the class as follows:
```using System.IO;
using System.Web.Mvc;
using System.Collections.Generic;
using TrafficTicketsSystem1.Models;
using System.Runtime.Serialization.Formatters.Binary;

namespace TrafficTicketsSystem1.Controllers
{
public class CamerasController : Controller
{
// GET: Cameras
public ActionResult Index()
{
FileStream fsCameras = null;
BinaryFormatter bfCameras = new BinaryFormatter();
string strCamerasFile = Server.MapPath("~/App_Data/Cameras.tts");

// If a file for Cameras records was proviously created, open it
if (System.IO.File.Exists(strCamerasFile))
{
{
/* After opening the file, get the list of records from it
* and store in the declared LinkedList<> variable. */
}
}

return View(cameras);
}

. . .
}
}```

Introduction to a Node as an Object

Introduction

As mentioned already, it is a tradition to call an item of a linked list a node. To define a node as a true object, the .NET Framework provides a sealed class named LinkedListNode:

`public sealed class LinkedListNode<T>`

This class has only properties, no methods.

The Value of a Node

Probably the most important aspect of a node is its value. To support it, the LinkedListNode class has a property named Value:

`public T Value { get; set; }`

Because this is a read-write property, you can use its write-accessory to specify or change its value. On the other hand, you can access the value of a node using this property.

Fundamental Operations on a Linked List

The Number of Nodes of a List

The LinkedList class starts as follows:

```public class LinkedList<T> : ICollection<T>,
IEnumerable<T>,
ICollection, IEnumerable,
ISerializable,
IDeserializationCallback```

As you can see, the LinkedList class implements the ICollection interface. This gives it a Count property that produces the number of nodes. Here is an example of accessing it:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Exercise()
{
List<double> values = new List<double>();

ViewData["NumberOfItems"] = numbers.Countt;
return View();
}
}
}
----------------------------------
@{
ViewBag.Title = "Exercise";
}

<h2>Exercise</h2>

@{
<p>The list contains @ViewData["NumberOfItems"] numbers.</p>
}```

This would produce:

The primary operation to perform on a linked list is to add a new node to it. To support this operation, the LinkedList class is equipped with various methods. One of them is named AddLast that is overloaded in two versions. One of them uses the following syntax:

`public LinkedListNode<T> AddLast(T value);`

This method expects the new value as argument. Here is an example of calling it:

```public ActionResult Exercise()
{

return View();
}```

Another version of this method is:

`public void AddLast(LinkedListNode<T> node);`

This version expects a LinkedListNode object as argument. Here is an example of calling it:

```public ActionResult Exercise()
{

return View();
}```

In the same way, you can call the LinkedList.AddLast() method to add new items. Here are examples:

```public ActionResult Exercise()
{

return View();
}```

1. Click the ViolationsTypesController.cs tab to access the class
2. Change the second Create() method as follows:
```using System.IO;
using System.Web.Mvc;
using System.Collections.Generic;
using TrafficTicketsSystem1.Models;
using System.Runtime.Serialization.Formatters.Binary;

namespace TrafficTicketsSystem1.Controllers
{
public class ViolationsTypesController : Controller
{
// GET: ViolationsTypes
public ActionResult Index()
{
FileStream fsViolationsTypes = null;
BinaryFormatter bfViolationsTypes = new BinaryFormatter();
string strViolationsTypesFile = Server.MapPath("~/App_Data/ViolationsTypes.tts");

// If a file for violations types was proviously created, open it
if (System.IO.File.Exists(strViolationsTypesFile))
{
{
/* After opening the file, get the list of records from it
* and store in the declared LinkedList<> variable. */
}
}

return View(categories);
}

// GET: ViolationsTypes/Details/5
public ActionResult Details(int id)
{
return View();
}

// GET: ViolationsTypes/Create
public ActionResult Create()
{
return View();
}

// POST: ViolationsTypes/Create
[HttpPost]
public ActionResult Create(FormCollection collection)
{
try
{
// TODO: Add insert logic here
FileStream fsViolationsTypes = null;
BinaryFormatter bfViolationsTypes = new BinaryFormatter();
string strViolationsTypesFile = Server.MapPath("~/App_Data/ViolationsTypes.tts");

if (!string.IsNullOrEmpty(collection["ViolationName"]))
{
if (System.IO.File.Exists(strViolationsTypesFile))
{
{
}
}

ViolationType vt = new ViolationType()
{
ViolationName = collection["ViolationName"],
Description = collection["Description"],
};

using (fsViolationsTypes = new FileStream(strViolationsTypesFile, FileMode.Create, FileAccess.Write, FileShare.Write))
{
bfViolationsTypes.Serialize(fsViolationsTypes, categories);
}
}

return RedirectToAction("Index");
}
catch
{
return View();
}
}

. . .

}
}```
3. Right-click inside any of the Create() methods -> Add View...
4. In the Add View dialog box, make sure the View Name text box is displaying Create.
5. Create its form as follows:
```@model TrafficTicketsSystem1.Models.ViolationType

@{
ViewBag.Title = "Create Violation Type";
}

<h2 class="common-font text-center bold maroon">Create Violation Type<</h2>

<hr />

@using (Html.BeginForm())
{
@Html.AntiForgeryToken()

<div class="large-content">
<div class="form-horizontal common-font">
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.ViolationName, htmlAttributes: new { @class = "control-label col-md-5 maroon" })
<div class="col-md-7">
@Html.EditorFor(model => model.ViolationName, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.ViolationName, "", new { @class = "text-danger" })
</div>
</div>

<div class="form-group">
@Html.LabelFor(model => model.Description, htmlAttributes: new { @class = "control-label col-md-5 maroon" })
<div class="col-md-7">
@Html.TextArea("Description", null,
htmlAttributes: new { @class = "form-control", rows = "10", cols = "20" })
@Html.ValidationMessageFor(model => model.Description, "", new { @class = "text-danger" })
</div>
</div>

<div class="form-group">
<div class="col-md-5"></div>
<div class="col-md-7 text-center">
<input type="submit" value="Save this Violation Type" class="btn btn-warning" />
</div>
</div>
</div>
</div>
}
<hr />
<p class="text-center">
@Html.ActionLink("Description of a Violation Type", "Details") ::
@Html.ActionLink("Edit/Update a Violation Type", "PrepareEdit") ::
</p>```

Looking for a Node

A Linked List that Contains a Certain Node

Because the LinkedList class implements the ICollection interface, it inherits the Contains method. As a reminder, its syntax is:

`public bool Contains(T value);`

This method checks whether the linked list contains the (a) node that has the value passed as argument. If that node is found, the method returns true. Otherwise it returns false. Here is an example of calling it:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{

return View();
}

public ActionResult Exercise()
{
string conclusion = string.Empty;

List<double> values = new List<double>();

if (numbers.Contains(2222.06) == true)
conclusion = "the list contains 2222.06.";
else
conclusion = "there is no such a number in the list.";

ViewData["Message"] = conclusion;

return View();
}
}
}
--------------------------------------------
@{
ViewBag.Title = "Exercise";
}

<h2>Exercise</h2>

<p>After examining the list, we can conclude that @ViewData["Message"]</p>```

This would produce:

This method works only if the type of the node is able to perform the comparison for equality. If you are using values of a primitive type (int, char, double, DateTime, etc) or string, the method would work fine. If you are using your own class, you should (must) override the Equals() method.

Finding a Node

While the LinkedList.Contains() method is used to find out whether a linked list has a certain value, it doesn't produce that value. If you want to get the actual node that has that value, you can call the LinkedList.Find() method. Its syntax is:

`public LinkedListNode<T> Find(T value);`

When this method is called, it starts looking for the value in the linked list. If it finds it, it returns its node. If there is more than one node with that value, the method returns only the first node that has that value. Here is an example of calling this method:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{

return View();
}

public ActionResult Exercise01()
{
string conclusion = string.Empty;

List<double> values = new List<double>();

if (numbers.Find(2747.06) != null)
conclusion = "2747.06 was found in the list.";
else
conclusion = "2747.06 is nowhere in the list.";

ViewData["Message"] = conclusion;

return View();
}
}
}
----------------------------------------------
@{
ViewBag.Title = "Exercise";
}

<h2>Exercise</h2>

<p>After examining the list, we can conclude that @ViewData["Message"]</p>```

This would produce:

Finding the Last Node

If the list contains more than one node that has the value but you prefer to use the last node, you can call the FindLast() method.

`public LinkedListNode<T> FindLast(T value);`

Once again, remember that these two methods are ready to work on primitive types. If you are using your own class for the type of node, you should (must) override the Equals() method.

Getting Each Node

As you can see, the LinkedList class doesn't implement the IList interface, which means it doesn't have an Item property. As we have seen with the AddLast() method and as we will see in the next sections, each method used to add a node is provided in two versions. One of the versions returns a LinkedListNode object. This means that, when performing an addition operation, you can get the returned value and do what you want with it.

The LinkedList class implements the IEnumerable interface. This makes it possible to use foreach to access each node. This can be done as follows:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{

return View();
}

public ActionResult Exercise()
{

ViewData["ChefSpecial"] = foodItems;

return View();
}
}
}
------------------------------------------------
@{
}

<p>Our restaurant offers the following menu:</p>

<ul>
@{
foreach (string food in ViewData["ChefSpecial"] as LinkedList<string>)
{
<li>@food</li>
}
}
</ul>```

This would produce

Navigating Among the Nodes

The First and the Last Nodes

As mentioned already, a linked list has a first and a last nodes (some people or documentations call them the head and the tail). To identify the first node, the LinkedList class is equippped with a read-only property named First. Its syntax is:

`public LinkedListNode<T> First { get; }`

The last node is represented by a read-only property of the same name and that, too, is a LinkedListNode object:

`public LinkedListNode<T> Last { get; }`

Here are examples of accessing these properties:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Exercise01()
{

ViewData["Numbers"] = numbers;
ViewData["First"]   = "The value of the first node is " + numbers.First.Value;
ViewData["Last"]    = "The value of the last node is " + numbers.Last.Value;

return View();
}
}
}
-----------------------------------------------
@{
ViewBag.Title = "Numbers";
}

<h2>Numbers</h2>

<ul>
@{
foreach (double nbr in ViewData["Numbers"] as LinkedList<double>)
{
<li>@nbr</li>
}
}
</ul>

<hr />

<p>@ViewData["First"]</p>

<p>@ViewData["Last"]</p>```

This would produce:

The Next and Previous Nodes

To access a node that is next to an existing node, you must first know what node is used as reference. To let you access the next node, the LinkedListNode class is equipped with a read-only property named Next:

`public LinkedListNode<T> Next { get; }`

To let you access the node previous to an existing one, the LinkedListNode class is equipped with the read-only Previous property:

`public LinkedListNode Previous { get; }`

Remember that in both cases, you need a node as reference.

Creating Nodes

Introduction

When dealing with a linked list, you have many options on how to add a new node. As mentioned already, a linked list has a first node, a last node, and one or more nodes between them. All nodes have and use some references with regards to the node(s) close to them. Based on this, when adding a new node, you have to specify whether you want it as the first node, the last node, the node before a certain node, or the node after a certain one. The LinkedList class easily supports all these operations with very little effort on your part.

We saw that you could call the AddFirst() method to add a new node. In reality, there is no such a thing as simply adding a new node to a linked list. When a linked list has just been created and it is empty, it holds a reference to a null node. There is nothing you can do with that node and you don't need to do anything with it. To start adding nodes, you have the option of setting it as the first or the last item. This would not make any difference because there is no other node in the list.

After adding a node, it becomes a reference that new nodes can use. If you call the AddFirst() method, the new node would be added before any existing node in the collection.

1. In the Solution Explorer, under Controllers, click CamerasController.cs
2. Implement the second Create() method as follows:
```using System.IO;
using System.Web.Mvc;

{

BinaryFormatter bfCameras = new BinaryFormatter();
string strCamerasFile = Server.MapPath("~/App_Data/Cameras.tts");

To let you add a node as last, the LinkedList is equipped with a method named AddLast. It is overloaded with versions whose syntaxes are:

```public LinkedListNode<T> AddLast(T value);

When you call this method, the value or node you pass will be added as the last item in the list. Here is an example:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Exercise01()
{
List&lt;double&gt; values = new List&lt;double&gt;();

ViewData[&quot;Numbers&quot;] = numbers;

return View();
}
}
}
------------------------------------------------
@{
ViewBag.Title = "Numbers";
}

<h2>Numbers</h2>

<ul>
@{
foreach (double nbr in ViewData["Numbers"] as LinkedList<double>)
{
<li>@nbr</li>
}
}
</ul>```

This would produce:

Nodes Maintenance in a Linked List

Inserting a Node Before a Referenced One

A linked list supports the concept of inserting a node but not exactly like traditional collections do it. With a linked list, you must add a node before or after an existing node used as reference.

Behind the scenes, before inserting a node, you must identify the position where you want to put it. That is, you must identify what node you will use as reference:

In this case, you want to insert a new node before the Other Node. Behind the scenes, the reference between the two existing nodes must be brocken. Then the new node points to the Other Node as its next and the Other Node points at the New Node as its previous:

After the new node has been added, it must point to the previous node (Some Node in our example) as its previous item. The previous node (Some Node in our example) must now point to the new node as its next item:

As you may imagine, to insert a node, you must provide two pieces of information: a reference to the node that will succeed the new node, and the new node (or its value). If the referenced node is the first item of the list, the new node would become the new first object.

To assist you with this operation, the LinkedList class provides a method named AddBefore. This method is overloaded with two versions whose syntaxes are:

```public void AddBefore(LinkedListNode<T> node, LinkedListNode<T> newNode);

In both cases, you pass a first argument as an existing node. In the first case, you must pass the LinkedListNode object that will be inserted the node. Here is an example:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Exercise01()
{
List<double> values = new List<double>();

ViewData["Numbers"] = numbers;

return View();
}
}
}```

This would produce:

In the second version, you directly pass the value to be positioned before node.

Inserting a Node After a Referenced One

Instead of inserting a node before an existing one, you can add it after one. The approach is logically the same as inserting a node before another, except that the sequence is reversed. First identify the node that will be used as reference. Start the process to add the new node after that one. Behind the scenes, the referenced node will point to the new node as its next and the new node will point to the existing node as its previous:

After the new node as been added, it will point to the node after it as its next. The other node will point to the new node as its previous:

If the new node is added after the last node, the new node will become the new last node.

To let you insert a node after an existing node, the LinkedList class is equipped with a method named AddAfter. It comes in two versions and their syntaxes are:

```public void AddAfter(LinkedListNode<T> node, LinkedListNode<T> newNode);

The arguments follow the same description as the AddBefore() method, only in reverse. Here is an example:

```using System.Web.Mvc;
using System.Collections.Generic;

namespace Exercise1.Controllers
{
public class HomeController : Controller
{
public ActionResult Exercise01()
{
List<double> values = new List<double>();

ViewData["Numbers"] = numbers;

return View();
}
}
}```

This would produce:

Deleting Nodes

Deleting the First or Last Node

When it comes time to deleting a node, you have many options, such as deleting the first or the last node of the list. To let you delete the first node, the LinkedList class provides the RemoveFirst() method. Its syntax is:

`public void RemoveFirst();`

As you can see, this method takes no argument. When it is called:

• If the list is empty, the compiler throws an InvalidOperationException exception:
• If the list contains one node, that node gets deleted
• If the list contains more than one node, the first one gets deleted

To delete the last node, you can call the RemoveLast() method whose syntax is:

`public void RemoveLast();`

This method follows the same logic as the RemoveFirst() method, only in reverse. Here are examples of calling these methods:

```@{
ViewBag.Title = "Numbers";
}

<h2>Numbers</h2>

@{
List<double> values = new List<double>();

}

<h3>First Series</h3>

<ul>
@{
foreach (double nbr in numbers)
{
<li>@nbr</li>
}
}
</ul>

<hr />

@{
numbers.RemoveFirst();
numbers.RemoveLast();
}

<h3>Second Series</h3>

<ul>
@{
foreach (double nbr in numbers)
{
<li>@nbr</li>
}
}
</ul>```

This would produce:

Removing a Node by Value

There are two ways you can delete an item inside the collection. This can be done using the Remove() method. It comes in two versions. If you know the exact value of the item you want to remove, you can call the following version of that method:

`public bool Remove(T value);`

When calling this method, pass the value to delete. The compiler would first look for a node that has that value:

• If there is a node with that value in the list, it would be deleted
• If there is no node with that value, nothing would happen (the compiler would not throw an exception)

An alternative is to delete a node based on its reference. To do this, use the following version:

`public void Remove(LinkedListNode<T> node);`

When calling this method, pass a reference to the node you want to delete. Here is an example:

```@{
ViewBag.Title = "Numbers";
}

<h2>Numbers</h2>

@{
List<double> values = new List<double>();

}

<h3>First Series</h3>

<ul>
@{
foreach (double nbr in numbers)
{
<li>@nbr</li>
}
}
</ul>

<hr />

@{
numbers.Remove(number275775);
}

<h3>Second Series</h3>

<ul>
@{
foreach (double nbr in numbers)
{
<li>@nbr</li>
}
}
</ul>```

 Violation Name Description Speed The vehicle drove at a speed significantly above the speed limit. The laws in this state require that every non-emergency and non-utility vehicle drives at or below the posted speed limit (or at or below the default speed regulation where the speed is not clearly posted). Stop Sign The vehicle did not stop at the Stop sign. The law in our state indicates every non-emergency vehicle to completely stop at every Stop sign, regardless of the presence or absence of incoming or adjacent vehicles. Red Light Steady The vehicle drove through a steady red light. The law in our state requires that when a vehicle approaches a steady red light, it must completely stop and wait for the light to change to green. Red Light Flashing The vehicle drove through a red light that was flashing (or blinking). The laws in this state require that if a vehicle comes to a flashing red light, whether it is at an intersection or not, the vehicle must first stop complete, the drive must observe around for pedestrians, animals, and other cars, and then cautiously. Red Light Right Turn The vehicle turns to the right without stopping. The laws in our state require that, when a vehicle reaches a traffic light and wants to make a right turn, if the light is red, regardless of any presence or not of another vehicle or pedestrian, the vehicle must first stop completely, and then make the right turn.
