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.
WebTwo subtrees are duplicate if and only if they have the same structure with the same node values. For example: In the below binary tree : The duplicate subtrees are {{2, 3}, {3}} … WebApr 1, 2016 · To check for duplicate subtree tree we first need to uniquely identify each subtrees. A binary tree can be constructed uniquely from a given inorder and postorder traversal reference . With this theory we can …
WebBinary Search Trees [ CLR 13 ] ... Each node in the BST has below it a left subtree and a right subtree. ... Whether to permit duplicate keys depends upon the application that uses the BST. Example. In the tree below, the root contains key 35, every key in the left subtree of the root is less than 35 (these are 11, 20, and 29), and every key in ... 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.
