WebJun 3, 2024 · A binary tree is a recursive data structure where each node can have 2 children at most. A common type of binary tree is a binary search tree, in which every node has a value that is greater than or equal to the node values in the left sub-tree, and less than or equal to the node values in the right sub-tree. WebPractice this problem. We can easily build a BST for a given postorder sequence by recursively repeating the following steps for all keys in it, starting from the right. Construct the root node of BST, which would be the last key in the postorder sequence. Find index i of the last key in the postorder sequence, which is smaller than the root node.
