Dqueues, also known as Deques or Double-ended Queues, are a data structure that generalizes a queue. Unlike a standard queue where elements can only be added or removed from one end (typically the rear and front, respectively), a deque allows for insertions and deletions at both ends. This means elements can be added to the front or rear, and removed from the front or rear.
Dqueues are a valuable tool in computer science for problems that require efficient access to both the
The operations typically supported by a deque include adding an element to the front (push_front), adding an
