Solution: Symmetric Tree

Explore how to determine whether a binary tree is symmetric by using a breadth-first search approach. This lesson guides you through checking subtree mirrors, managing nodes with a queue, and understanding the algorithm's efficiency in terms of time and space.

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]
