Hey! Wanted to share a beautiful combinatorics problem — the best short-answer problem I've seen recently. Try it when you have 15 minutes to spare since your submission will be timed :)
Beautiful Combinatorics Problem
Hope you all enjoy! There is a solution on the 'post-contest' screen.
Hmmm, not suspicious at all...
I added it onto the site as a contest because of how beautiful it was haha

Yep, it's very nice
It is pretty cool. It reminds me of another one I saw that went like this:
You are an archer and you have to pop three columns of balloons. One column contains $$$2$$$ balloons and the other two columns contain $$$3$$$ balloons. You can pop a balloon from any column, but unfortunately, you can only pop the bottommost balloon in some column. In how many different ways can you pop all the balloons?
mine is this

Good profile photo, may I ask the hex code?
