Question 876. Middle of the Linked List Solution 题目大意:求链表的中间节点 思路:构造两个节点,遍历链接,一个每次走一步,另一个每次走两步,一个遍历完链表,另一个恰好在中间 Java实现: public ListNode middleNode(ListNode head) { ListNode slow = head; ListNode fast = head; while (fast != null) { fast = fast.next; i…
Given a non-empty, singly linked list with head node head, return a middle node of linked list. If there are two middle nodes, return the second middle node. Example 1: Input: [1,2,3,4,5] Output: Node 3 from this list (Serialization: [3,4,5]) The ret…
