Add Two Numbers Total Accepted: 160702 Total Submissions: 664770 Difficulty: Medium You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the t…

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…
