Solution: Symmetric Tree

Explore how to check whether a binary tree is symmetric by applying a breadth-first search approach. This lesson guides you through the queue-based algorithm for comparing left and right subtrees, helping you understand the implementation and efficiency considerations. Learn to analyze time and space complexity in this practical tree problem solution.

We'll cover the following...

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]
