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: [9, 27, 40, 16, 4, 10, 38, 1, 45, 23, 25, 31, 14, 21, 34, 36, 37, 28, 22, 33], target=18
Solution:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
