Hello there /sci/ if you're smart as you say I have a math problem for you. Don't worry it'll be trivial for you if you're actually smart and no wannabe smart. So, here comes the problem:
Twenty random cards are placed in a row all face down. A turn consists of taking two adjacent cards where the left one is face up and the right one can be face up or face down and flipping them both. Show that this process must terminate. (with all the cards facing up).
And for you who will say it's my homework. No it isn't. So waiting for your answers. Good luck. Pic unrelated.

not clear to me... so first turn you flip the left one then you flip both?

Sorry for mistake. When you turn one card you turn other card to the right of that card you just turned. Example:
You have two face down cards, when you turn one to the left, up you must turn other card too.

I guess my question is too hard for your brain. And you're calling me brainlet.

so do you only turn over face up cards after the first turn?

Kek. The fuck? One of my classmates gave me that question. I guess he found it there.

>>9031729
You turn one card and it doesn't matter if the card to the right is face up or down, you turn it.
>>
>>9031686
well lets not look at this as cards, think of it as a binary code with the face downs as 1s and the fac eups as 0s
