Discrete Logging

Description

Given a prime P, 2 <= P < 231, an integer B, 2 <= B < P, and an integer N, 1 <= N < P, compute the discrete logarithm of N, base B, modulo P. That is, find an integer L such that
BL == N (mod P)
Input

Read several lines of input, each containing P,B,N separated by a space.
Output

For each line print the logarithm on a separate line. If there are several, print the smallest; if there is none, print "no solution".
