Given a positive integer n, write a program to find out a nonzero multiple
m of n whose decimal representation contains only the digits 0 and 1. You may
assume that n is not greater than 200 and there is a corresponding m containing
no more than 100 decimal digits.
The input file may contain multiple test cases. Each line contains a value of
n (1 <= n <= 200). A line containing a zero (0) terminates the input.
For each value of n in the input print a line containing the corresponding value
of m. The decimal representation of m must not contain more than 100 digits.
If there are multiple solutions for a given value of n, any one of them is acceptable.
