Extra credit: what does the following Python function do? 1% is the mod operator. " is integer division, i.e. division, followed by floor. For example, 7 % 3 evaluates to 1, 7 1/3 evaluates to 2. Put differently, both functions execute the division algorithm; II finds the quotient, % the remainder. def function(b,n,d) defines a function with inputs b,n and d.] def function (b,n,d) result 1 while n 0 resul t = result*b % d return result It returns bn mod d using slow modular exponentiation It returns bn mod d using fast modular exponentiation It executes the ivision algorthm drnbr and retums the value r resu) It return gcd(b, n, d) It executes the division algorithm n=bd+r and returns the value of r ("resulst") It return Icm(b, n, d) It returns the lowest common prime factor of b, n and d
