    572 - Subtree of Another Tree.

    Easy

    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 root tree is in the range [1, 2000].
    • The number of nodes in the subRoot tree is in the range [1, 1000].
    • -104 <= root.val <= 104
    • -104 <= subRoot.val <= 104
