Grokking the Coding Interview Patterns

Symmetric Tree

Explore how to identify symmetric trees by understanding their mirrored structure around the root. Learn to apply breadth-first search to efficiently check tree symmetry, solidifying your grasp on tree traversal patterns used in coding interviews.

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 a mirror of itself, i.e., symmetric around its root.

Constraints:

  • The tree contains nodes in the range [1,500][1, 500]
