Find N Unique Integers Sum Up To Zero

findNUniqueIntegersSumUpToZero.js

/*
Given an integer n, return any array containing n unique integers such that they add up to 0.
 
Example 1:
Input: n = 5
Output: [-7,-1,1,3,4]
Explanation: These arrays also are accepted [-5,-1,1,2,3] , [-3,-1,2,-2,4].
Example 2:
Input: n = 3
Output: [-1,0,1]
Example 3:
Input: n = 1
Output: [0]
 
Constraints:
1 <= n <= 1000
