Quite simple and funny coding challenge to solve, well done.

I'd say yes to both questions about the buttons.

Okay, but how do I see the response for the earlier one? It's hidden.

Are the numbers transitional? That is if there's a "1010" then a 1 and the following 0, do they mean that the button was pressed and then released? So if there are 2 1s in succession like "110", then does that mean that the button is being held down?

No need to create a new issue about the same problem. Closing this one.

I can't read alexc19 answer, but I think the R is because of this other rule:

If two buttons are pressed simultaneously, the red button will be preferred.

There are examples but without explanations. So it's difficult to make sense out of it with the explanation above it. I see another user has reported the same but I can't see the response for thta because it's hidden as it's marked as spoiler.

you have something like: [1, -1, 6, -6, 5]
the reduce method give the number's sum, in this case it will be 5, and this is the correct answer.
But there is a problem maybe you have something like [1, -1, 6, -6, 5, 5], in this case the sum will be 10, because we have an additional 5, to avoid that, he has removed all the duplicated numbers in the array converting it to Set type

How does it work?

I wish I could set both "best practice" and "clever" together

The squares should be placed next to each other and NOT on top of each other. (my first idea ;-)

Okay there is a description but what is the purpose of this kata?
What are you expecting from players??
