BinaryTree

C# Binary tree

This project contains a cross platform Binary Tree implementation

Code Coverage

How to Install

You can directly install this library from Nuget. There is package:

BinaryTree

PM> Install-Package BinaryTree

How to use

Create a new instanse: var binaryTree = new BinaryTree<int>(); and add elements:

binaryTree.Add(8);
binaryTree.Add(5);
binaryTree.Add(12)

or use collection initializer like : var binaryTree = new BinaryTree<int>() { 8, 5, 12, 3, 7, 10, 15 };

Another way is constructs a BinaryTree, copying the contents of the given collection

IList<int> numbers = new List<int>();
var binaryTree = new BinaryTree<int>(numbers);

Also you can initialize a new instance of the BinaryTree class that is empty and has the specified initial capacity: var binaryTree = new BinaryTree<int>(10);

By default traversal is set to In-order

You can set the type of traversal in constructor var binaryTree = new BinaryTree<int>(new PostOrderTraversal<int>()); or use property TraversalStrategy:

var inOrder = new InOrderTraversal<int>();
var preOrder = new PreOrderTraversal<int>();
var postOrder = new PostOrderTraversal<int>();

binaryTree.TraversalStrategy = preOrder;

Available operations:

• void Add(T value) - adds a new element to the tree
• void AddRange(IEnumerable<T> collection) - copying the contents of the given collection to the tree
• ITraversalStrategy<T> TraversalStrategy -gets or sets type of traversal(Pre-order, In-order, Post-order)
• int Count - returns count of elements in tree
• int Capacity - gets the number of elements that the BinaryTree can contain
• bool IsReadOnly - always return false
• bool IsFixedSize - gets a value indicating whether the BinaryTree has a fixed size
• bool Contains(T value) - checks if the tree contains the element
• bool Remove(T value) - remove element from the tree. Returns true if element was removed.
• void Clear() - clears tree
• void CopyTo(T[] array, int arrayIndex) - copies all the elements of the tree to the specified one-dimensional array starting at the specified destination array index.
• IEnumerator<T> GetEnumerator() - returns numerator of tree

To display all elements of tree, use:

foreach (var item in binaryTree)
{
    Console.Write(item + " ");
}

or use extension method:

binaryTree.PrintToConsole();
