The Elves in accounting are thankful for your help; one of them even offers you a starfish coin they had left over from a past vacation. They offer you a second one if you can find three numbers in your expense report that meet the same criteria.

For example, again using the same expense report:

1721, 979, 979, 366, 299, 675, 1456

The three entries that sum to \(2020\) are \(979\), \(366\), and \(675\). Multiplying them together produces the answer, \(241861950\).

Assignment

Write a function repair that takes a sequence (list) of positive numbers (Int). The function must return the product (Int) of the three numbers in the sequence that sum to 2020.

Example

> repair [1721, 979, 979, 366, 299, 675, 1456]
241861950
