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: [13, 43, 25, 9, 27, 5, 39, 16, 49, 18, 17, 22, 10, 26, 1, 46, 41, 4, 32, 3], target=47
Student:
[25, 22]
