题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1002 解题思路:就是把大的数用数组存放起来,像小学的时候用竖式加法来算两个数相加那样算: 反思:思路很简单,可是有很多细节考虑不好,有时候没有进位,有时候又没有输出正确的答案,然后有时候数组长度又开小了什么的,所以还要多多练习. #include<stdio.h> #include<string.h> #define max 1000 void add(char a[],char b[…

/*A + B Problem II Problem Description I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B. Input The first line of the input contains an integer T(1<=T<=20) which means the number of test case…

从杭电第一题开始A,发现做到1002就不会了,经过几天时间终于A出来了,顺便整理了一下关于大数的东西 其实这是刘汝佳老师在<算法竞赛 经典入门 第二版> 中所讲的模板,代码原封不动写上的,但是经过自己的使用与调试也明白了其中的内涵. 首先定义大数的结构体: struct BigNum{ ; ; vector<int> s; BigNum(){ *this=num; } BigNum operator = (long long num){ s.clear(); //vector.cl…
