572. Subtree of Another Tree Easy

1/**
2 * [572] Subtree of Another Tree
3 *
4 * 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.
5 * 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.
6 *  
7 * Example 1:
8 * <img alt="" src="https://assets.leetcode.com/uploads/2021/04/28/subtree1-tree.jpg" style="width: 532px; height: 400px;" />
9 * Input: root = [3,4,5,1,2], subRoot = [4,1,2]
10 * Output: true
11 * 
12 * Example 2:
13 * <img alt="" src="https://assets.leetcode.com/uploads/2021/04/28/subtree2-tree.jpg" style="width: 502px; height: 458px;" />
14 * Input: root = [3,4,5,1,2,null,null,null,null,0], subRoot = [4,1,2]
15 * Output: false
16 * 
17 *  
18 * Constraints:
19 * 
20 * 	The number of nodes in the root tree is in the range [1, 2000].
21 * 	The number of nodes in the subRoot tree is in the range [1, 1000].
22 * 	-10^4 <= root.val <= 10^4
23 * 	-10^4 <= subRoot.val <= 10^4
24 *
