If there are two middle nodes, return the **second middle** node (the sublist starting from that node to the end). ### Constraints - The number of nodes in the list is in the range `[1, 100]`. - `1 <= Node.val <= 100` ### Input Format A single line containing space-separated integers representing the list. ### Output Format Print the space-separated integers of the sublist starting from the middle node.
