Challenge: Find Two Numbers That Add Up to "n"

Problem statement

In this problem, you have to implement the find_sum(lst, n) function which will take a list lst and number n as inputs and return two numbers from the list that add up to n.

Input

A list and a number n

Output

A list with two integers a and b that add up to n

Sample input

lst = [1, 21, 3, 14, 5, 60, 7, 6]
n = 81

Sample output

result = [21, 60]

For example, in this illustration, we are given 81 as the number n and when we traverse the whole list, we find that 21 and 60 are the integers that add up to 81.
