题目链接

Problem Description

Now give you two integers n m, you just tell me the m-th number after radix point in 1/n,for example n=4,the first numble after point is 2,the second is 5,and all 0 followed

 

 

Input

Each line of input will contain a pair of integers for n and m(1<=n<=10^7,1<=m<=10^5)

 

 

Output

For each line of input, your program should print a numble on a line,according to the above rules

 

 

Sample Input

4 25 7123 123

 

 

Sample Output

508

#include<iostream>using namespace std;int main(){    int n,m,t;    while(cin>>n>>m)    {        if(n==1)            cout<<"0"<<endl;        else        {            int sum=10;            while(m--)            {                 t=sum/n;                sum=sum%n*10;            }            cout<<t<<endl;        }    }    return 0;}
