这道题是LeetCode里的第160道题. 题目讲的: 编写一个程序,找到两个单链表相交的起始节点. 如下面的两个链表: 在节点 c1 开始相交. 示例 1: 输入:intersectVal = 8, listA = [4,1,8,4,5], listB = [5,0,1,8,4,5], skipA = 2, skipB = 3 输出:Reference of the node with value = 8 输入解释:相交节点的值为 8 (注意,如果两个列表相交则不能为 0).从各自的表头开始算…

找出链表的交点, 如图所示的c1, 如果没有相交返回null. A:             a1 → a2                               ↘                                   c1 → c2 → c3                              ↗            B:     b1 → b2 → b3 我的方法是: (1)统计两个链表的长度 (2)移动较长的链表的表头,使得让两个链表的长度一致 (3)从修正后…

题意: 给两个链表,他们的后部分可能有公共点.请返回第一个公共节点的地址?若不重叠就返回null. 思路: 用时间O(n)和空间O(1)的做法.此题数据弱有些弱. 方法(1)假设两个链表A和B,用两个指针分别按顺序遍历AB和BA,这AB和BA肯定等长的.如果他们有公共点,那么按照这样走必定会在某个点相遇.所以只要预先判断是否有公共点,这只需要用两个指针分别指向A和B的链尾判断是否相同即可(这一步可以使用更简单的方法,增加1个计数器,判断指针1是否已经遍历过AB了). /** * Definiti…
