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
