Description
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.
Input
The input file may contain multiple test cases. Each line contains a value of n (1 <= n <= 200). A line containing a zero terminates the input.
Output
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.
Sample Input
2

Sample Output

给定一个正整数 n,请编写一个程序来寻找 n 的一个非零的倍数 m,这个 m 应当在十进制表示时每一位上只包含 0 或者 1。你可以假定 n 不大于 200 且 m 不多于 100 位。
提示:本题采用 Special Judge,你无需输出所有符合条件的 m,你只需要输出任一符合条件的 m 即可。
