Program to create a binary search tree

Like Article. A utility function to search a given key in BST def search root,key : Base Cases: root is null or key is present at root if root is None or root. Insert root, 50 ; b. Insert root, 30 ; b. Insert root, 20 ; b. Insert root, 40 ; b. Insert root, 70 ; b. Insert root, 60 ; b. Insert root, 80 ; b. Here is the implementation of this logic. We know that an element lesser than the current node is always on its left side.

When we move to the left child of each node starting from root till end recursively, the smallest element will be present in the last. So, to find the smallest element of a binary search tree, we just have to find the leftmost element of the tree. In this article, we have seen underlying concepts behind binary search trees.

We have also implemented various operations like insertion, searching, finding the maximum element, and finding a minimum element in the binary search tree. I would encourage you to implement the codes and play with them. Stay tuned for more informative tutorials. Easy Normal Medium Hard Expert. Writing code in comment?
