Problem: Same Tree

Explore how to determine whether two binary trees are identical by applying recursive depth-first traversal. Learn to compare the structure and values of corresponding nodes efficiently, and understand the time and space complexity involved in this tree comparison problem.

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 ...
