WebThe idea is to traverse the tree in a postorder fashion and search for a given node in the tree. For any node, if the given node is found in either its left subtree or its right subtree, then the current node is an ancestor of it.

WebApr 8, 2010 · A Binary Search Tree has a very specific property: for any node X, X's key is larger than the key of any descendent of its left child, and smaller than the key of any descendant of its right child. A Binary Tree imposes no such restriction. A Binary Tree is simply a data structure with a 'key' element, and two children, say 'left' and 'right'. WebA binary tree with an integer value at each node is provided to you. (which might be positive or negative).

Since the problem revolves around binary trees, a particular node can have atmost 2 children so the ancestor of any given node will be its parent … WebBinary Trees. ¶. 1. Definitions and Properties ¶. A binary tree is made up of a finite set of elements called nodes . This set either is empty or consists of a node called the root together with two binary trees, called the left and right subtrees, which are disjoint from each other and from the root.
