However, it's worth noting that this implementation iterates through the array three times in the best case (once for sum(), once for max(), and once for min()), which could be a consideration for very large arrays where performance is critical.Maybe your solution was even better in the end ;)

Don't feel dumb. It's true there are better solutions than others, but you should feel proud because you completed the challenge! One can improve with time! :)

Same lol
