61. Rotate List
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 <= 1000 <= k <= 2 * 109
Solution
type ListNode struct {
Val int
Next *ListNode
}
