4 解决思路：从表头开始相加，记录每次相加的进位。5 具体算法：伪代码如下：初始化进位变量carry=0将p和q分别初始化为l1和l2的头部。循环遍历列表l1和l2，直到达到两端。 将x设置为节点p的值。如果p已达到l1的末尾，则设置为0。 将y设置为节点q的值。如果q已达到l2的末尾，则设置为0。 设置sum =...
隔了这么久,突然想起来刷 LeetCode,按着顺序到了第二题 —— Add Two Numbers。 题目: You are given twonon-emptylinked lists representing two non-negative integers. The digits are stored inreverse orderand each of their nodes contain a single digit. Add the two numbers and return it as a li...
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 leading zero, exc...
LeetCode 2. Add Two Numbers non-empty You may assume the two numbers do not contain any leading zero, except the number 0 itself. Input: (2 -> 4 -> 3) + (5 -> 6 -> 4) Output: answer: class Solution { public: ListNode* addTwoNumbers(ListNode* l1, ListNode* l2) {...
addTwoNumbers(l1, l2); 78 while (l != NULL){ 79 cout << l->val << endl; 80 l = l->next; 81 } 82 while (1); 83 } 运行结果: 因为是一边学C++,一边刷leetcode,所以有什么问题,十分感谢您能指点。 本文参与 腾讯云自媒体同步曝光计划,分享自作者个人站点/博客。 原始发表:2015-05-25 ,...
