Problem: Same Tree

Explore how to verify if two binary trees are identical by comparing their structure and node values through a recursive approach. Understand the use of depth-first traversal and base cases to efficiently solve this problem, and learn about its time and space complexity characteristics.

We'll cover the following...

Statement

Given the roots of two binary trees, p and q, determine whether the two trees are identical.

Two binary trees are considered the same if they share the same structure and every corresponding node contains the same value.

Constraints:

  • The number of nodes in each tree is in the range [0,100][0, 100].

  • −104≤-10^4 \leq Node.data ...
