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: [47, 49, 14, 12, 46, 1, 32, 36, 39, 24, 7, 19, 15, 17, 11, 13, 6, 3, 42, 10], target=47
Solution:
[46, 1]
