Neetcode: Subtree of Another Tree

Instructions

Given the roots of two binary trees root and subRoot, return true if there is a subtree of root with the same structure and node values of subRoot and false otherwise.

A subtree of a binary tree tree is a tree that consists of a node in tree and all of this node's descendants. The tree tree could also be considered as a subtree of itself.

Example 1:

Input: root = [1,2,3,4,5], subRoot = [2,4,5]

Output: true

Example 2:

Input: root = [1,2,3,4,5,null,null,6], subRoot = [2,4,5]

Output: false

Constraints:

• 1 <= The number of nodes in both trees <= 100
• -100 <= root.val, subRoot.val <= 100
