The problem is to determine if there are exactly 4 values in a list of values such that they sum to a value N. If there are, print true else print false.
Sample
List [1, 3, 5, 7] with N equal to 10 should print false. There are no four values that sum to 10.
List [1, 3, 5, 7] with N equal to 16 should print true. 1 + 3 + 7 + 5 = 16.
List [6, 1, 10, 3, 8, 2] with N equal to 19 should print true. 6 + 10 + 2 + 1 = 19.
List [1, 2, 3, 4, 5] with N equal to 6 should print false. Even though there are several groups of numbers that sum to 6, there is not a group of exactly 4 numbers that do so.
List [2, 2, 1, 1] with N equal to 6 should print true.
