索引 思路1:基本加法规则 思路2:移花接木法... 问题描述:https://leetcode.com/problems/add-two-numbers/ 思路1:基本加法规则 根据小学学的基本加法规则.....我们需要将两个数以最低位为基准对齐,然后逐个加,需要进位的给进位就行了....恰好这个链表是逆序的!!!已经为我们对齐了.用两个指针分别指向两个链表头,开始同步往后移动,边移动边计算结果,直到两个指针都到了尽头/没有进位.时间复杂度是O(max(m, n)),空间复杂度和时间复杂度一样…

1.题目描述 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 2.我的错误版本 2.1 解题思路 题中链表顺序正好是…
