scheme

d returns its maximum element. If the input list is empty, then it should 3. (4 points) The maxint function takes a list of numbers, an For example, (maxInt '(7 3 6 2)) should return 7. return 0. Write the maxInt function in Scheme in two steps: (a) (2 points) Write a maxInt helper function; it takes a num ber k and a list of numbers, z, as arguments, and returns the number which is the largest among k and numbers in r. For example, (maxInt helper 5 '(4 5 6)) should return 6. Define maxInt helper by case analysis and recursion
