Solution: Symmetric Tree

Understand how to check if a binary tree is symmetric by comparing left and right subtrees using a queue. This lesson guides you through the BFS algorithm that ensures the tree is a mirror of itself, helping you grasp traversal techniques and evaluate complexity in practical coding interviews.

Statement

Given the root of a binary tree, check whether it is a symmetric tree. A symmetric tree refers to a tree that is the mirror of itself, i.e., symmetric around its root.

Constraints:

  • The tree contains nodes in the range [1,500][1, 500]
