题目描述 给你两个单链表的头节点 headA 和headB ,请你找出并返回两个单链表相交的起始节点。如果两个链表不存在相交节点,返回 null 。 图示两个链表在节点 c1 开始相交: 题目数据 保证 整个链式结构中不存在环。 注意,函数返回结果后,链表必须保持其原始结构。 自定义评测: 评测系统 的输入如下(你设计的程序...
B: b1 → b2 → b3 Sincea == bis true, end loopwhile(a != b), return the intersection nodea = c1. Case 2 (Have Intersection & Different Len): a A: a1 → a2 ↘ c1 → c2 → c3 →null↗ B: b1 → b2 → b3 b a A: a1 → a2 ↘ c1 → c2 → c3 →null↗ B: b1 →...
1. If the two linked lists have no intersection at all, return null. 2. The linked lists must retain their original structure after the function returns. 3. You may assume there are no cycles anywhere in the entire linked structure. 4. Your code should preferably run in O(n) time and ...
Can you solve this real interview question? Intersection of Two Linked Lists - Given the heads of two singly linked-lists headA and headB, return the node at which the two lists intersect. If the two linked lists have no intersection at all, return null.
题目链接https://leetcode.com/problems/intersection-of-two-linked-lists/ 题意很好懂,问题在于如何找到相交的node,想到的最简单的方法从node的最后一个节点去往前数,遇到分叉,则返回当前节点,否则返回None。这里用 两个list去保存node,从list的最后一个位置开始往前进。 代码如下,提交后,超过 99.84% 提交代码的...
【leetcode76】Intersection of Two Arrays II 题目描述: 给定两个数组求他们的公共部分,输出形式是数组,相同的元素累计计数 例如: nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. 原文描述: Given two arrays, write a function to compute their intersection. Example: Given nums1 = [1...
