Teacher: 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
Teacher: Now, understand the problem? If you are still confused, see the following example:
[2,4,5,6,4,8,9,10], target=10
Solution: [2,8]
Reason: 2 and 8 are present in the list and sum to 10 which was the target sum

Now, solve this instance: [7, 12, 4, 2, 39, 33, 23, 38, 14, 44, 16, 49, 27, 5, 31, 47, 43, 24, 41, 18], target=81
Student:
[38, 43]
