Add Two Numbers: You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numbers do not contain any...
Add Two Numbers - LeetCode 注意点 考虑位数不一样的情况以及首位有进位的情况 解法 解法一:模拟加法,用变量carry保存进位。遍历链表,先算长度相同的部分,然后算长度多出来的那部分,随时要更新carry的值。最后判断carry的值因为会有首位进位的情况。时间复杂度为O(n) /** * Definition for singly-linked list....
