Before the how, the why: what problem queues deques solve, and what it costs you to get them wrong. We start from a concrete ...

When to reach for queues deques — and when not to. The design tradeoffs, side by side. We compare queues deques against the ...

The invariants of queues deques: the facts that must stay true after every operation. We state each invariant plainly and show how ...
