I know the test cases don't cover it, but what if at least one of them was 0? ;-)

There is a description conflict.

That's really clever!

wait, I think I know. it's adding the numbers, then sorting them so 2 + 2 > 7 so false, etc. ?

Can someone explain what is going on? A little confused on this solution

It could work as long as you call it with exactly 3 parameters. The problem is when you call it with different number of parameters. In those case (a, b, c) version will raise an ArgumentError because the function requiers exactly 3 parameter. Your soultion will raise nil related errors if you call it less then 3 parameters, which is misleading, but it will NOT raise any error in the case of more then 3 parameters. And this latter means it may hide a coding error.

Thank you for the reminder~

Next time please mark the comment as spoilers if you're posting solution code ;-)

Well... with your latest change the same code that I had just worked fine.

Thanks!

I added some debug output to the reuby code, please try again.

Also, 4 people already solved it, so it should be working...

I've included an explanation of array lengths tested. I hope it's helpfull.
