1367 - Linked List in Binary Tree\. Medium Given a binary tree `root` and a linked list with `head` as the first node. Return True if all the elements in the linked list starting from the `head` correspond to some _downward path_ connected in the binary tree otherwise return False. In this context downward path means a path that starts at some node and goes downwards. **Example 1:** **** **Input:** head = [4,2,8], root = [1,4,4,null,2,2,null,1,null,6,8,null,null,null,null,1,3] **Output:** true **Explanation:** Nodes in blue form a subpath in the binary Tree. **Example 2:** **** **Input:** head = [1,4,2,6], root = [1,4,4,null,2,2,null,1,null,6,8,null,null,null,null,1,3] **Output:** true **Example 3:** **Input:** head = [1,4,2,6,8], root = [1,4,4,null,2,2,null,1,null,6,8,null,null,null,null,1,3] **Output:** false **Explanation:** There is no path in the binary tree that contains all the elements of the linked list from `head`. **Constraints:** * The number of nodes in the tree will be in the range `[1, 2500]`. * The number of nodes in the list will be in the range `[1, 100]`. * `1 <= Node.val <= 100` for each node in the linked list and binary tree.
