A Binary Search Tree (BST) is a binary tree in which all the elements stored in the left subtree of node x are less then x and all elements stored in the right subtree of node x are greater then x. return false; There exists many data structures, but they are chosen for usage on the basis of time consumed in insert/search/delete operations performed on data structures. }. } int data; getchar(); Here, we will focus on the parts related to the binary search tree like inserting a node, deleting a node, searching, etc. left child node’s value is always less than the parent Note. else #include Binary search tree (BST) is a special type of tree which follows the following rules −.
