Write a function max of type int list -> int that returns the largest element of a list of integers. Your function need not behave well if the list is empty. Hint: Write a helper function maxhelper that takes as a second parameter the largest element seen so far. Then you can complete the exercise by defining fun max x = maxhelper (t1 x, hd x); Write a function max of type int list -> int that returns the largest element of a list of integers.
