Swap function in Haskell

Question

I'm starting my adventure with Haskell language and I need a little help. How should I define swap function which is declared:

swap :: (Int, Char) -> (Char, Int)

Probably it's very easy, but I have problem with that.

Answer 1

You can also be more general with:

swap :: (a, b) -> (b, a)
swap (x, y) = (y, x)

This works for all types, not just for Int and Char.
