Post order in binary search tree
Web12 Dec 2024 · Approach: In postorder traversal, the tree is traversed in this way: left, right, root. The algorithm approach can be stated as: We first recursively visit the left child and go on left till we find a node pointing to NULL. Then we return to its parent. Then we recursively visit the right child. Web22 Sep 2024 · A binary search tree ( BST) is a sorted binary tree, where we can easily search for any key using the binary search algorithm. To sort the BST, it has to have the following properties: The node's left subtree contains only a key that's smaller than the node's key. Scope This article tells about the working of the Binary search tree.
