I try to solve the 99 haskell problems on several ways.
But my first try which looks like this :
gives the following error message :
src/Main.hs at 1:1-1:6
Invalid type signature: Last2 :: [a] -> a Should be of form <variable>
What am trying to do is say the input is a list which can be of integers
or chars so everything is the output can then also be of type everything.
