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:
\n\n\n\n
\nInput: head = [4,2,8], root = [1,4,4,null,2,2,null,1,null,6,8,null,null,null,null,1,3]\nOutput: true\nExplanation: Nodes in blue form a subpath in the binary Tree. \n\n\n
Example 2:
\n\n\n\n
\nInput: head = [1,4,2,6], root = [1,4,4,null,2,2,null,1,null,6,8,null,null,null,null,1,3]\nOutput: true\n\n\n
Example 3:
\n\n\nInput: head = [1,4,2,6,8], root = [1,4,4,null,2,2,null,1,null,6,8,null,null,null,null,1,3]\nOutput: false\nExplanation: There is no path in the binary tree that contains all the elements of the linked list from head
