题目意思很简单,两个链表分别表示两个数,将两个数相加的结果存入一个新的链表中. 思路同样很简单:两个链表如果一样长,对应位置相加,如果某一个链表多了,则根据加的结果有无进位继续处理,全部结束后要考虑会不会还剩进位. c++的链表,题目已经给了一个挺好的例子: struct ListNode { int val; ListNode *next; ListNode(int x) : val(x), next(NULL) {} }; 对于创建链表可以使用一个头节点来一直指向这个链表,头节点中没有数据…

反向存储,从左往右加 ［抄题］: 你有两个用链表代表的整数,其中每个节点包含一个数字.数字存储按照在原来整数中相反的顺序,使得第一个数字位于链表的开头.写出一个函数将两个整数相加,用链表形式返回和.给出两个链表 3->1->5->null 和 5->9->2->null,返回 8->0->8->null [暴力解法]: 时间分析: 空间分析: ［思维问题］: 直接从左往右加就行,没看出来. 链表结构改变时要添加dummy,返回的是dummy.next…
