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: [38, 16, 6, 20, 32, 28, 26, 40, 3, 36, 15, 29, 30, 19, 47, 10, 23, 39, 4, 25], target=67
Student:
[38, 29]
