Solution: Symmetric Tree

Explore how to use breadth-first search to check if a binary tree is symmetric around its root. This lesson guides you through implementing an algorithm that compares left and right subtrees using a queue, covering edge cases and providing time and space complexity analysis.

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]
