Given the head of a singly linked list, rotate the list to the right by k places. Example 1: Input: head = [1,2,3,4,5] k = 2 Output: head = [4,5,1,2,3] Explanation: We have to rotate the list to the right twice. Example 2: Input: head = [1,2,3] k = 4 Output: head = [3,1,2] Explanation: The list [1,2,3] rotated right by 1 is [3,1,2]. The list [1,2,3] rotated right by 2 is [2,3,1]. The list [1,2,3] rotated right by 3 is [1,2,3]. The list [1,2,3] rotated right by 4 is [3,1,2].
