Binary Search Tree. So when you try to insert 15 again, it will not do anything. Binary search tree shouldn't have duplicates.
Also try practice problems to test & improve your skill level. In computer science, a binary search tree (bst), also called an ordered or sorted binary tree, is a rooted binary tree whose internal nodes each store a key greater than all the keys in the node's left subtree and less than those in its right subtree. Find mode in binary search tree. Binary search tree is just another binary tree with the twist where the scanned input goes either to the left or to the right of the root node also called as the parent node.
A binary tree where the left child contains only nodes with values less a binary search tree of size 9 and depth 3, with 8 at the root.
You can see the implementation of a bst in. So when you try to insert 15 again, it will not do anything. Number of distinct binary search trees possible with 3 distinct keys. Also, you will find working examples of binary search tree in c, c++, java, and python.
