2.2 Implement an algorithm to find the kth to last element of a singly linked list. 这道题让我们求链表中倒数第k个元素,LeetCode中相类似的题目有Kth Largest Element in an Array 数组中第k大的数字 和 Kth Smallest Element in a BST 二叉搜索树中的第K小的元素.但那两道题和这题又不一样,首先这道题是要在链表中操作,链表的特点就是不能通过下标来直接访
class LNode { public LNode next; public int data; } /*找出倒数第k个元素,只遍历一遍*/ class Kk { private static LNode head = new LNode();; private static LNode node; private static LNode tail; private static LNode fast; private static LNode slow; private static in
