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
5
0
8
这个是区间数列的问题麽？这不是求1/n中小数点后的第m个数字的问题麽？
