[5 points] Fix the incorrect definition of function flipcase below. It's supposed to take a character and flip it from lowercase to uppercase (or vice versa). If the character is not a letter, flipcase should just return its argument. E.g. we should get map flipcase "abCDE0123;?!"- "ABcde0123;2! If you're working in ghci, you should add the module Data.Char using :m Data.Char at the ghci fore trying to define fli Don't use if-else expressions: Practice using patterns and guards [5 points] Fix the incorrect definition of function flipcase below.
