Did you miss the <pseudo-code> bit?

Any text book on data structures will detail a Stack
How many will discuss a Deque

The documentation for Deque states

"A linear collection that supports element insertion and removal at both 
ends"

Not exactly stack like is it?

It's the idea, not the actual implementation that is important.
If the OP can read he can figure the rest out for himself
