摘要： Problem DescriptionI have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B.InputThe first line of the input contains an integer T(1#include using namespace std;int main(){ char x[1001],y[1001];//用来存放输入的两个数，第一个大数存在x里面，第二个大数存在y里面 int xx[1001]={... 阅读全文

摘要： Problem Description求A^B的最后三位数表示的整数。说明：A^B的含义是“A的B次方”Input输入数据包含多个测试实例，每个实例占一行，由两个正整数A和B组成（1using namespace std;int main(){ int x,y,i; int m=1; while(cin>>x>>y&&x&&y) { for(i=0;i<y;i++) { m=m*x; m=m%1000;//因为只关心最后三位,所以每次都把得到的结果取最后三位与下一个m相乘 } ... 阅读全文

摘要： Problem DescriptionWe all love recursion! Don't we?Consider a three-parameter recursive function w(a, b, c):if a 20 or b > 20 or c > 20, then w(a, b, c) returns:w(20, 20, 20)if a using namespace std;int main(){ int w[21][21][21];//要比20大 int i,j,k; for(i=0;i>a>>b>>c&& 阅读全文

摘要： 问题描述：输入多组数据，输出其二进制的形式，以输入0 结束程序。解法：循环。用一个数组来存放每次运算的余数，每次运算指的是被除数 除以 2 ，每得到一个余数就放到数组里面，一直运算知道被除数等于0为止，输出二进制要从数组里逆序输出。代码：#include using namespace std;int a[100];//数组用来存放余数int main(){ int beichushu,yushu,i=1; while(cin>>beichushu&&beichushu!=0)//多次输入，以0结束程序 { while (beichushu!=0) ... 阅读全文

摘要： Description给出一个不多于5位的整数，要求 1、求出它是几位数 2、分别输出每一位数字 3、按逆序输出各位数字，例如原数为321,应输出123Input一个不大于5位的数字Output三行第一行 位数第二行 用空格分开的每个数字，注意最后一个数字后没有空格第三行 按逆序输出这个数#include using namespace std;int main(){ int n; int a,b,c,d,e; cin>>n; a=n/10000; b=(n-10000*a)/1000; c=(n-10000*a-1000*b)/100; d=(n-1... 阅读全文
