( 129 ) E The very same Munchhausen PROGRAMMING brute force 3000

B'A positive integer a is given. Baron Munchausen claims that he knows such a positive integer n that if one multiplies n by a , the sum of its digits decreases a times. In other words, S(an) = S(n)/a , where S(x) denotes the sum of digits of the number x . Find out if what Baron told can be true. The only line contains a single integer a ( 2 <= a <= 10^3 ). If there is no such number n , print -1 . Otherwise print any appropriate positive integer n . Your number must not consist of more than 5 cdot10^5 digits. We can show that under given constraints either there is no answer, or there is an answer no longer than 5 cdot10^5 digits. '...
