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 = [3,4,5,1,2], subRoot = [4,1,2] Output: true
Example 2:
Input: root = [3,4,5,1,2,null,null,null,null,0], subRoot = [4,1,2] Output: false
Constraints:
- The number of nodes in the
roottree is in the range[1, 2000]. - The number of nodes in the
subRoottree is in the range[1, 1000]. -104 <= root.val <= 104-104 <= subRoot.val <= 104
