Input: Inorder traversal in[] = {4, 2, 5, 1, 3, 6} Preorder traversal pre[] = {1, 2, 4, 5, 3, 6} Output: Postorder traversal is {4, 5, 2, 6, 3, 1} A naive solution is to first construct the given tree, then rec

Full binary tree is a BST. Solution Approach A simple solution to the problem is to perform in-order traversal of the tree. And for each node of the tree, check if its subtrees are BST or not. At last return the size of the largest subtree which is a BST. Advertisement - This...
Given a binary tree root and an integer target, delete all the leaf nodes with value target. Note that once you delete a leaf node with value target, if it’s parent node becomes a leaf node and has the value target, it should also be deleted (you need to continue doing that until ...
