Problem: Same Tree

Explore how to check if two binary trees are identical by recursively comparing node values and structure. Understand how to implement this using depth-first traversal and analyze the time and space complexities involved.

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 ...
