The function shuffle2 :: [Int] -> [Int] -> [Int] takes in two lists of numbers and interleaves them, taking two from the first list, then one from the second list. When one list runs out the rest of the other list is output. shuffle2 [10,20,30,40] [100,200,300] == [10,20,100,30,40,200,300] (either24 :: [Int] -> Bool) Given an array of ints, return true if the array contains a 2 next to a 2 or a 4 next to a 4, but not both.

The makes function takes in a number n and a list of numbers xs. It returns the number of ways to make n by adding the first number in the list to some other number later in the list. makes :: Int -> [Int] -> Int makes 12 [6,6] == 1 makes 11 [8,3,11,3] == 2 makes 2 [1,1,1,1] == 3 Continue to Chapter 4 Discussion IV.
