Problem :

Write a function max3 of type int*int*int -> int that returns the largest of three integers.

Problem :

Write a function second of type ‘a list -> ‘a that returns the second element of a list. Your function need not behave well on lists with less than two elements.

Problem :

Write a function permute of type ‘a list -> ‘a list whose output list is the same as the input list, but with the first two elements of the list swapped. For example: permute ([1,2,3,4]) should return [2,1,3,4] or permute([“a”,”b”,”c”]) should return [“b”,”a”,”c”]

Solution

(* Write a function permute of type ‘a list -> ‘a list whose output list is the same as the input list, but with the first two elements of the list swapped. *)
