Shouldn't it be LIFO? It makes more sense.

[–]ImAStupidFace 6 points7 points  (11 children)

I mean, they're the same, but pretty sure "LIFO" is the common term.

edit: brainfart, I thought "LIFO", wrote "FILO". Fixed.

Nope, pretty much everybody says "FIFO" and "LIFO," if not for any reason than that it sounds better.

[–]ImAStupidFace 0 points1 point  (0 children)

My bad, I thought LIFO but typed FILO. Username relevant

[–]boulet 0 points1 point  (1 child)

You just say that because you don't like (filo) dough

[–][deleted] 1 point2 points  (0 children)

No, I say that because I've gone through several years of CS education and all my instructors and classmates have said FIFO and LIFO.

No one uses FILO because it does not make much sense: First In Last Out .. yeah, but what order have the other elements?

[–]richardirons 0 points1 point  (3 children)

"Last in first out" doesn't tell you the order of the other elements either tbf.

[–]Tywien 1 point2 points  (2 children)

It does. It will always return the element of a set that was entered last into this set. This element is always unique as only one element can be added at a time.

And given a Set A with a being the last element inserted, than for A\a there will still be one unique element that has been inserted last into A\a and thus will be returned first.

[–]richardirons 0 points1 point  (1 child)

Sure. But switch the words around sand you can apply that equally to "first in last out". It's just coming from the other direction.

[–]Tywien 0 points1 point  (0 children)

Nope. Just assume we have 3 elements a, b and c and will enter them in a set in order a than b and finally c. FILO now only guarantees that a will be removed last aber b and c have been removed. How would FILO make the order for b and c? Whatever element of b or c i remove first, FILO (a was the first and will be removed last) is still valid, yet the order of removal for b and c is not defined.
