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: [29, 6, 2, 15, 49, 13, 36, 44, 43, 21, 1, 30, 10, 23, 12, 48, 41, 47, 32, 39], target=83
Solution:
[36, 47]
