/**
 * [61] Rotate List
 *
 * Given a linked list, rotate the list to the right by k places, where k is non-negative.
 *
 * Example 1:
 *
 *
 * Input: 1->2->3->4->5->NULL, k = 2
 * Output: 4->5->1->2->3->NULL
 * Explanation:
 * rotate 1 steps to the right: 5->1->2->3->4->NULL
 * rotate 2 steps to the right: 4->5->1->2->3->NULL
 *
 *
 * Example 2:
 *
 *
 * Input: 0->1->2->NULL, k = 4
 * Output: 2->0->1->NULL
 * Explanation:
 * rotate 1 steps to the right: 2->0->1->NULL
 * rotate 2 steps to the right: 1->2->0->NULL
 * rotate 3 steps to the right: 0->1->2->NULL
 * rotate 4 steps to the right: 2->0->1->NULL
