You are given a list of integers and an integer target, return a list of a pair of numbers in any order such that they add up to target. If there is no such pair of numbers, then return an empty list
Example: [2,4,5,6,4,8,9,10], target=10
Example solution: [2,8]
Example explanation: 2 and 8 are present in the list and sum to 10 which was the target sum

Problem: [9, 29, 39, 26, 8, 31, 34, 35, 46, 48, 7, 23, 1, 3, 10, 19, 44, 2, 6, 43], target=100
