编写一个程序,找到两个单链表相交的起始节点.例如,下面的两个链表:A:           a1 → a2                            ↘                                c1 → c2 → c3                            ↗            B:  b1 → b2 → b3在节点 c1 开始相交.注意:    如果两个链表没有交点,返回 null.    在返回结果后,两个链表仍须保持原有的结构.   …

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…

160. Intersection of Two Linked Lists[easy] Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists: A: a1 → a2 ↘ c1 → c2 → c3 ↗ B: b1 → b2 → b3 begin to intersect at n…
