Array-Sum-Pairs Challenge

In this challenge, you need to implement a function that receives an array of integers (both positive and negative) and returns the first pair of integers that add up to form a given sum.

As an example:

getPairs([3, 4, 7, 6], 10); // Must return [3, 7]

Notes

• If no valid pair of integers can be found, return undefined
• Your implementation must work for several different arrays of variadic length
• Your implementation will also run against an array of 5.000.000 integers
