You can also use other predefined functions, of course, but do not write any additional named functions and do not use explicit recursion. If you need helper func- tions, use anonymous ones. For example, if the problem says "write a function add2 that takes an int list and returns the same list with 2 added to every ele- ment," your answer should be fun add2 x- map (fn a a 2) x; You have seen some of these problems before. The trick now is to solve the new, concise form. m in this
