May 2, 2024 · If the root node is NULL, return true as an empty binary tree is considered symmetric. Create a queue and push the root node twice into the queue. While the queue is not empty, dequeue two nodes at a time, one for the left subtree and one for the right subtree.

Given a Binary Tree. Check whether it is Symmetric or not, i.e. whether the binary tree is a Mirror image of itself or not. Example 1: Input: 5 / \ 1 1 / \ 2 2 Output: True Explan
A tree is said to be a mirror image of itself if there exists an axis of symmetry through a root node that divides the tree into two same halves. Table of Contents. Example. Types of Solution for Symmetric Tree. Recursive. Approach. Algorithm for Symmetric Tree. Implementation for Symmetric Tree. C++ Program for Symmetric Tree.
Mar 18, 2024 · A binary tree is symmetric if the root node’s left subtree is a mirror reflection of the right subtree. For example, the following binary tree is symmetric: The following binary tree is not symmetric, although the two subtrees have the same tree structure: 3. Recursive Solution.
Jul 31, 2023 · A symmetric tree is a binary tree where the left and right sub-trees of each node are identical in structure and the values of the corresponding nodes are also equal. In simpler terms, a symmetric tree can be folded in half along its center and the two halves match each other.
