Can someone explain the joke? I know what stacks are but I don’t get it…

It's the last element, so it has to wait for all the other elements on top of it to be popped in order to be accessed

I think op meant last as in the element on the bottom

Yea, I meant the last element as in the one at the bottom, but now I see that it‘s a little confusing…

[–] Gentoo1337 1 points 1 year ago

Yea I also thought the last one was the bottom one but then I remembered it was lifo

Oh ok I guess that makes sense. Was it that obvious? 😅

Maybe it's something about not knowing if the last element is the top of the stack or the bottom of the stack?

Split the difference, it is the only element in a deque.

He looks like he's guarding something? A sentinel value in an array-based stack implementation in C or something? I don't know, I'm a bit confused too.
