prev  |  next  |  chance

Given an integer array "arr", return a new array, but with these four rules applied.

1. Remove all negative numbers
2. Remove all odd numbers
3. Remove all duplicate numbers
4. Sort all of the numbers from least to greatest


array_fourRules([-1, -1, 0, 0, 1, 1, 2, 2, 3, 3]) → [0, 2]
array_fourRules([1, 2, 3, 1, 2, 3, 0, 0, -1, -1]) → [0, 2]
array_fourRules([1, 2, 3, 4, 5, 5, 4, 3, 2, 1]) → [2, 4]

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

public int[] array_fourRules(int[] arr) { }
