Duplicate subtree in a binary tree
WebDec 12, 2024 · Given a binary tree with N number of nodes, check if that input tree is BST (Binary Search Tree). If yes, return true, return false otherwise. Note: Duplicate elements should be kept in the right subtree. Input format : The first line of input contains data of the nodes of the tree in level order form. The data of the nodes of the tree is ... WebJun 19, 2009 · Assumption made is T1 and T2 are binary tree without any balancing factor. 1) Search the root of T2 in T1. If not found T2 is not a subtree. Searching the element in BT will take O (n) time. 2) If the element is found, do pre-order traversal of T1 from the node root element of T2 is found. This will take o (n) time.

WebFeb 28, 2024 · The inorder traversal for both trees would be 1 -> 2 -> 3. Simply put, inorder traversal won't guarantee uniqueness. That's why your solution returns an incorrect answer. Using preorder/postorder traversal does not guarantee uniqueness either. If you include "null" nodes in your traversal, then they'll give a unique string for each tree. WebAnswer (1 of 3): Create a 2d arrays flag[][], where flag[i][j] means if sub-tree i and sub-tree j is the same. (sub-tree i refers to the sub-tree whose root is node i) If i, j are leaves, obviously flag[i][j] = True. If i is a leaf and j is not, obviously flag[i][j] = …
