Solution: Symmetric Tree

Explore the method to determine if a binary tree is symmetric by using breadth-first search. This lesson helps you understand the queue-based algorithm to compare left and right subtrees level by level, ensuring you grasp the time and space complexity involved in this tree traversal technique.

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].
  • 103-10^3 \le
