2. (25 pts) The mathematical operation min (x, y) can be represented by the conditional expression In a similar fashion, using only conditional expressions, describe the mathematical operations a=min(x,y,z) and a=max(x,y,z) Hint: You may 3. (25 pts) Write a program that reads in an integer value for n and then sums the integers from a to 2 n if n is nonnegative, or from 2nto n if n is negative. Write the code in two versions: one using only for loops and the other using only while loops 4. (25 pts) Write an interactive program that asks the user to supply three integers k, m, and n, with k being greater than 1. Your program should compute the sum of all the integers between m and n that are divisible by k use if statements
