Grokking the Coding Interview Patterns in Python

Same Tree

Understand how to implement a function that checks if two binary trees are structurally identical and have the same node values. Learn to develop an efficient solution running in linear time and space, enhancing your algorithm skills for coding interviews.

We'll cover the following...

Statement

Given the roots of two binary trees, p and q, write a function to check whether or not they are the same. Two binary trees are considered the same if they’re structurally identical and the nodes have the same value.

Constraints:

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