题目描述

A positive integer aa is given. Baron Munchausen claims that he knows such a positive integer nn that if one multiplies nn by aa , the sum of its digits decreases aa times. In other words, S(an)=S(n)/aS(an) = S(n)/a , where S(x)S(x) denotes the sum of digits of the number xx .

Find out if what Baron told can be true.

输入格式

The only line contains a single integer aa ( 2a1032 \le a \le 10^3 ).

输出格式

If there is no such number nn , print 1-1 .

Otherwise print any appropriate positive integer nn . Your number must not consist of more than 51055\cdot10^5 digits. We can show that under given constraints either there is no answer, or there is an answer no longer than 51055\cdot10^5 digits.
