Same Tree

Leetcode problem 100; Difficulty: Easy

Problem Statement

Given the roots of two binary trees p and q, write a function to check if they are the same or not.

Two binary trees are considered the same if they are structurally identical, and the nodes have the same value.

Constraints:

• The number of nodes in the tree is in the range [1, 100].
• -104 <= Node.val <= 104

Example 1:

Input: p = [1,2,3], q = [1,2,3]

Output: true

Example 2:

Input: p = [1,2], q = [1,null,2]

Output: false

Example 3:

Input: p = [1,2,1], q = [1,1,2]

Output: false
