Binary Search Tree program for Insertion, Deletion, and Traversal in C

This post focuses on the Binary search tree (BST) and the implementation of a Binary Search Tree program for Insertion, Deletion, and Traversal in C.

What is a Binary Search Tree (BST)?

It is one of the most used data structure where the nodes are placed together in a tree-like structure. Tree-like structure refers to the structure where there is a parent node and each parent is linked with its child nodes. But in BST a parent node cannot have more than two child nodes. The top node being the root node in the structure.

NOTE:
The child nodes on the left of its parent node are equal to its parent node.
The child nodes in the right of its parent node are greater than its parent node.

Binary search tree

In the above diagram, the right side binary tree isn’t binary search tree because the node “4” contains a higher value than its sub-node.
