Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists: begin to intersect at node c1. Example 1: Input: intersectVal = 8, listA = [4,1,8,4,5], listB = [5,0,1,8,4,5], skipA = 2, skipB ...
skipB =2Output:nullInput Explanation:Fromthe headofA, it readsas[2,6,4].Fromthe headofB, it readsas[1,5]. Since the two listsdonotintersect, intersectVal must be0,whileskipAandskipB can be arbitrary values.Explanation:The two listsdonotintersect, soreturnnull. ...
输入:intersectVal = 2, listA = [0,9,1,2,4], listB = [3,2,4], skipA = 3, skipB = 1输出:Intersected at '2'解释:相交节点的值为 2 (注意,如果两个链表相交则不能为 0)。 从各自的表头开始算起,链表 A 为 [0,9,1,2,4],链表 B 为 [3,2,4]。在 A 中,相交节点前有 3 个...

思路1 http://bookshadow.com/weblog/2014/12/04/leetcode-intersection-two-linked-lists/ 判断交点是否存在 如果两个链表有交点,则它们的最后一个节点一定是同一个节点。所以当pA/pB到达链表末尾时,分别记录下A和B的最后一个节点。如果两个链表的末尾节点不一致,说明两个链表没有交点。

Next challenges: (M) Linked List Cycle II 二.Linked List Cycle II Total Accepted: 61662 Total Submissions: 196038 Difficulty: Medium Given a linked list, return the node where the cycle begins. If there is no cycle, return null. Note: Do not modify the linked list. Follow up:Can you ...
intersectVal == listA[skipA + 1] == listB[skipB + 1]iflistAandlistBintersect. Follow up:Could you write a solution that runs inO(n)time and use onlyO(1)memory? 解法一: 解法一是通过计算出两条链表的长度差,通过缩短两者的长度差从而使得两者同时到达第一个共同结点. ...
LeetCode 160. Intersection of Two Linked Lists 题意:不改变两个原始链表A,B的情况下找到两个链表开始重叠的那个节点,若没有重叠,则返回NULL; 解法:假设A,B的长度分别为A.length=a+c,B.length=b+c,重叠的长度为c。因为a+c+b+c = b+c+a+c,即a+c+b = b+c+a,那么在最后还剩c个节点的时候...
LeetCode 160. Intersection of Two Linked Lists题目分析 其他 请写一个程序,找到两个单链表最开始的交叉节点。 ** 注意事项 ** 如果两个链表没有交叉,返回null。 在返回结果后,两个链表仍须保持原有的结构。 可假定整个链表结构中没有循环。 样例 下列两个链表: ...
