我现在在做一个叫<leetbook>的免费开源书项目,力求提供最易懂的中文思路,目前把解题思路都同步更新到gitbook上了,需要的同学可以去看看 书的地址:https://hk029.gitbooks.io/leetbook/ ` 2.Add Two Numbers [M] Add Two Numbers M 题目 思路 代码 更精巧的代码 题目 You are given two linked lists representing two non-negative numbers. The…
题目: 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 num…
题目大意:使用链表表示的两个整数,计算出其和,以同样的形式返回. Input: (2 -> 4 -> 3) + (5 -> 6 -> 4) Output: 7 -> 0 -> 8 觉得做OJ最大的问题是有时看不懂题目. 其实是这样的,一个链表代表一个非负整数数,是从右往左看的: (2 -> 4 -> 3) = 342: (5 -> 6 -> 4)=465: 342+465=7 -> 0 -> 8=807: 逆序其实是很大很大的便利!!…
1.题目描述 2.分析 首先将链表翻转,然后做加法. 最后将结果链表翻转. 3.代码 ListNode* addTwoNumbers(ListNode* l1, ListNode* l2) { ListNode* L1 = reverseList( l1 ); ListNode* L2 = reverseList( l2 ); ListNode* head = ); ListNode* result = head; ListNode* p1 = L1; ListNode* p2 = L2; ;…
1.题目描述 2.题目描述 题目思路可以参考合并单链表的思路,定义一个全局 进位标志,如果两个数值相加得到需要进位,则将进位标志置为1 . 3.代码 ListNode* addTwoNumbers(ListNode* l1, ListNode* l2) { ListNode* head = ) ; ListNode* result = head; ListNode* p1 = l1; ListNode* p2 = l2; ; while( p1 != NULL && p2 != NULL…
