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