Medium

---

Given the head of a linked list, rotate the list to the right by k places.

Example 1:

Input: head = [1,2,3,4,5], k = 2
Output:
 [4,5,1,2,3]

Example 2:

Input: head = [0,1,2], k = 4
Output:
 [2,0,1]

Constraints:

• The number of nodes in the list is in the range [0, 500].

• -100 <= Node.val <= 100

• 0 <= k <= 2 * 109
