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.
WebA Binary Search Tree (BST) is a binary tree in which each vertex has only up to 2 children that satisfies BST property: All vertices in the left subtree of a vertex must hold a value smaller than its own and all vertices in the right subtree of a vertex must hold a value larger than its own (we have assumption that all values are distinct integers in this visualization … gripper shower curtain rodWebFeb 28, 2024 · Find Duplicate Subtrees - Given the root of a binary tree, return all duplicate subtrees.
