Super Numbers

Euler's phi function for a positive integer N is usually denoted as φ(N) and defined as the number of positive integers less than or equal to N that are coprime with N. Let's call a positive integer N a super number if N can be divided by φ(N) without a remainder. e.g. 2 is a super number (since 2 mod φ(2) = 0), while 3 is not (since 3 mod φ(3) = 1). You are given two positive integers L and R. Y
