Boolean logic in Haskell 3. Haskell provides boolean operators: (&&) :: Bool -> Bool -> Bool (II) :: Bool -> Bool -> Bool The parentheses here mean these are infix functions. So you can write True && False for example. 4. Define a function isInRange :: Integer -> Integer -> Integer -> Bool where isInRange a b c returns true if c is between the two inputs a and b (or equal to either of them) and false otherwise. 5. Define a function xor to compute the exclusive OR function, including its type signature
