E. Vasya and Polynomialtime limit per test2 secondsmemory limit per test256 megabytesinputstandard inputoutputstandard outputVasya is studying in the last class of school and soon he will take exams. He decided to study polynomials. Polynomial is a function P(x) = a0 + a1x1 + ... + anxn. Numbers ai are called coefficients of a polynomial, non-negative integer n is called a degree of a polynomial.Vasya has made a bet with his friends that he can solve any problem with polynomials. They suggested him the problem: "Determine how many polynomials P(x) exist with integer non-negative coefficients so that , and , where  and b are given positive integers"? Vasya does not like losing bets, but he has no idea how to solve this task, so please help him to solve the problem.InputThe input contains three integer positive numbers  no greater than 1018.OutputIf there is an infinite number of such polynomials, then print "inf" without quotes, otherwise print the reminder of an answer modulo 109 + 7.ExamplesInput2 2 2Output2Input2 3 3Output1
