2017 ACM-ICPC 亚洲区（西安赛区）网络赛C. Sum

题目

Define the function S(x) for xx is a positive integer. S(x) equals to the sum of all digit of the decimal expression of x. Please find a positive integer k that S(k∗x)%233=0.

Input Format

First line an integer T, indicates the number of test cases (T≤100). Then Each line has a single integer x(1≤x≤1000000) indicates i-th test case.

Output Format

For each test case, print an integer in a single line indicates the answer. The length of the answer should not exceed 2000. If there are more than one answer, output anyone is ok.

样例输出

89999999999999999999999999

思路 直接输出233个9。因为任何正整数乘以9的数位和都是9的倍数

AC代码

#include <iostream>
using namespace std;
int main()
{
    int T,n;
    cin>>T;
    while(T--){
        cin>>n;
        for(int i=1;i<=233;i++){
            cout<<9;
        }
        cout<<endl;
    }
    return 0;
}
