1. Given n, the number of input register bits in decimal form, two primes p and q, and a number b, write a (classical) C/C++ program that calculates f(x) = b*mod N. (Note that p and q must each be less than 2/2 which is an input condition.) The program consists of two principal processing modules: (a) The first processing module determines the binary expansion of x. (b) The second processing module calculates f(x) = b*modN using the %3D binary expansion of x.
