Solution: Symmetric Tree

Explore the method to determine if a binary tree is symmetric by using breadth-first search. Understand how to compare mirrored nodes iteratively with a queue, ensuring the tree's left and right subtrees mirror each other. This lesson helps you implement an O(n) time complexity solution to verify symmetry in trees, crucial for coding interviews involving tree traversal patterns.

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]
