Haskell Programming

-- 1. Fill in the gaps. Complete the following definitions. It does not

-- matter what the definitions do as long as they are type correct. For e1, e2,

-- e5, and e7, this means uncommenting the type declaration and replacing the ? with

-- type(s) correspond to the definitions directly below them. For e3, e4,

-- e6, and e8, this means replacing the undefined with an expression of appropriate type.

--

-- Note: you should complete each definition one at a time.

--e1 :: ?

e1 = [True,False,True]

--e2 :: ?

e2 = [[1,2],[3,4]]

e3 :: (Char,Bool)

e3 = undefined

e4 :: [(String,Int)]

e4 = undefined

--e5 :: ? -> ?

e5 n = n*2

e6 :: Int -> Int -> Int

e6 = undefined

--e7 :: ? -> ?

e7 (x,y) = (y,x)

e8 :: a -> (a,a)

e8 = undefined
