YT新人之巅峰大决战03

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 2
5 7
123 123

#include<Iostream>
using namespace std;
int main()
{ int n,m,i,s,a,t;
while(cin>>n>>m)
{
if(m==1)
cout<<0<<endl;
else
{s=10;
for(i=1;i<=m;i++)
{

t=s/n;
s=s%n*10;

}
cout<<t<<endl;
}

}
return 0;

}

Sample Output
