F#:

Write a function

explode : string -> char list so that explode s returns the list of characters in s: explode "star" = [s;t;a;r] Hint: if s is a string then s.ToCharArray() returns an array of characters. You can then use List.ofArray to turn it into a list of characters. Now write a function explode2 : string -> char list similar to explode except that you now have to use the string function s.Chars (or .[]), where s is a string. You can also make use of s.Remove(0,1). The definition of explode2 will be recursive.
