部分翻转 => prev = ListNode

ListNode prev = xxx;ListNode currentNode = prev.next;while (currentNode != null) {     ListNode temp = currentNode.next;     currentNode.next = temp.next;     temp.next = prev.next;     prev.next = temp;}

public class Demo {    public boolean enoughK(int k, ListNode head) {        for (int i = 0; i < k; i++) {            if (head == null) {                return false;
