Can someone help me with these and show me how to run them on something like Standard ML of New Jersey?

1.Write a function sqsum of type int ! int that takes an non-negative integer n and returns the sum of the squares of all the integers 0 through n. Your function need not behave well on negative input.

2. 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. (refer to exercise 13 on page 85 of the textbook)
