De-dupling numbers from array
Challenge 7 - Medium
Description
The idea here is that we are going to get an array of numbers, those numbers can be duplicated and are not going to be in a specific order. For example:
0
1
const input = [1, 9, 7, 5, 4, 4, 9, 12, 6, 8, 8, 4, 9, 3, 2]
Objective
We want to return an object with three arrays in it:
- multiple an array of the numbers that are duplicated.
- only_once an array of the numbers that appear only once.
- unique an array of the numbers without that appear, without their dupesnpm.
