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: [43, 48, 13, 35, 22, 3, 24, 23, 47, 2, 33, 29, 30, 44, 34, 14, 5, 12, 40, 19], target=33
Student:
[3, 30]
