Problem: Same Tree

Explore how to determine if two binary trees are identical by using recursive depth-first traversal. Understand the process of comparing node values and tree structures step-by-step while analyzing time and space complexities related to tree height and node count.

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 ≤ ...
