Writingg on Haskell

1. Using the previous function, convert each tuple to a product of its two elements, using foldl and a lambda expression.

2. Using scanl, write a function that takes a list of Ints and make a list of cumulative sums.

3. Consider this function:

applyThrice :: (Int -> Int) -> Int -> Int applyThrice f x = f (f (f x))

Use $ to make the second line more readable
