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
One example: [2,4,5,6,4,8,9,10], target=10
Solution is here: [2,8]
Explanation: 2 and 8 are present in the list and sum to 10 which was the target sum

Now, solve this: [39, 23, 7, 28, 26, 41, 45, 31, 19, 22, 43, 14, 48, 44, 18, 5, 8, 40, 12, 37], target=78
Solution:
[41, 37]
