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