nemesisInTheHouse


Define a function that when passed an Arraylist, returns,
- true, if each item has its negated value (6 and -6 are mutual negatives, for example), and,
- false, otherwise.


nemesisInTheHouse([6, -6, -6]) → true
nemesisInTheHouse([0, 0, -5, 8, 3, 5, 5, -8, 8, 8, 8, -8]) → false
nemesisInTheHouse([-3, 0, 0, -5, 8, 3, 5, 5, -8, 8, 8, 8, -8, -3]) → true

...Save, Compile, Run (ctrl-enter)

boolean nemesisInTheHouse(ArrayList<Integer> data) { }
