给定两个非空链表来代表两个非负整数.数字最高位位于链表开始位置.它们的每个节点只存储单个数字.将这两数相加会返回一个新的链表.你可以假设除了数字 0 之外,这两个数字都不会以零开头.进阶:如果输入链表不能修改该如何处理?换句话说,你不能对列表中的节点进行翻转.示例:输入: (7 -> 2 -> 4 -> 3) + (5 -> 6 -> 4)输出: 7 -> 8 -> 0 -> 7详见:https://leetcode.com/problems/add-two…

Leetcode算法系列(链表)之两数相加 难度:中等给出两个 非空 的链表用来表示两个非负的整数.其中,它们各自的位数是按照 逆序 的方式存储的,并且它们的每个节点只能存储 一位 数字.如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和.您可以假设除了数字 0 之外,这两个数都不会以 0 开头.示例:输入:(2 -> 4 -> 3) + (5 -> 6 -> 4)输出:7 -> 0 -> 8原因:342 + 465 = 807 链接:https://le…

大家好,我是编程熊,今天是LeetCode每日一题的第二天,一起学习的是LeetCode第二题<两数相加>. 题意 给你两个 非空 的链表,表示两个非负的整数.它们每位数字都是按照 逆序 的方式存储的,并且每个节点只能存储 一位 数字. 请你将两个数相加,并以相同形式返回一个表示和的链表. 你可以假设除了数字 0 之外,这两个数都不会以 0 开头. 示例 输入:l1 = [2,4,3], l2 = [5,6,4] 输出:[7,0,8] 解释:342 + 465 = 807. 题解 因为链表是逆…

题目描述: Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. Example: Given nums = [2, 7, 1…
