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

 

Sample Output

　　水题，但也要动动脑子。

　　模拟除法的运算。输入两个数n和m，求出1/n的小数点后的第m位数。

　　代码：

 #include <iostream>

 using namespace std;
 int main()
 {
     int n,m;
     while(cin>>n>>m){
         if(n==){
             cout<<<<endl;
             continue;
         }
         int num = ;
         int d = ;
         int dn = ;
         while(d!=m){
             dn = num/n;
             num = num%n;
             num*=;
             ++d;
         }
         cout<<dn<<endl;
     }
     return ;
 }
