By using this, we construct the binary search tree and then perform the post-order traversal of the tree, starting with the left subtree of the root node, then visiting the right subtree and finally the root node. The post-order traversal of the binary search tree is A C E D G F B I J H.

WebA binary tree is a data structure in which each node has at most two child nodes; one on the left and one on the right. The root node is the topmost node and all other nodes are its descendants. Each node can contain a key, which is used to compare and sort elements. The left child of a node is always less than the key of the parent node, while ... Web14 apr. 2024 · Given the root of a binary tree, determine if it is a valid binary search tree (BST).
