8.
Consider the function
palindrome xs = reverse xs == xs
What is its type? (5 points). Why are there the particular class
constraints on "xs"? (5 points)
9.
Consider the function
twice f x = f (f x)
What is its type? (5 points). What constraints does "twice" place on
the type that function "f" can be? (5 points)
Hint: try seeing what happens when we call "twice head [1,2,3]" in
GHCi
