01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第37题(顺位题号是160)。编写程序以找到两个单链表交叉的节点。例如: 以下两个链表: A: a1→a2 ↘ c1→c2→c3 ↗ B:b1→b2→b3 链表A和链表B在c1处相交。 注意: 如果两个链接列表根本没有交集,则返回null。 函数返回后,链接列表必须保留其原始结构。

先算出两个链表各自的长度,然后从较长的链表先遍历,遍历到较长链表剩余长度和较短链表一样时,用两个指针同时遍历两个链表。这样如果链表有交点的话,两个指针已经一定会相遇。 代码 public class Solution { public ListNode getIntersectionNode(ListNode headA, ListNode headB) { ListNode nodea = headA, nodeb...
