An output-restricted deque is one where insertion can be made at both ends, but deletion can be made from one end only. Both the basic and most common list types in computing, queues and stacks can be considered specializations of deques, and can be implemented using deques.
Queues may be implemented as a separate data type, or maybe considered a special case of a double-ended queue (deque) and not implemented separately. For example, Perl and Ruby allow pushing and popping an array from both ends, so one can use push and shift functions to enqueue and dequeue a list (or, in reverse, one can use unshift and pop ...
deque is a container class template that implements a double-ended queue. It provides similar computational complexity to vector for most operations, with the notable exception that it provides amortized constant-time insertion and removal from both ends of the element sequence.
In computer science, a priority queue is an abstract data type similar to a regular queue or stack abstract data type. Each element in a priority queue has an associated priority.
Unlike C++'s deque, the O(1) performance guarantee includes the time complexity of working with the block list, whereas the C++ standard only guarantees the deque to be O(1) in terms of operations on the underlying value type. The monoque consists of a size variable and a fixed-size block list of blocks with exponentially increasing sizes.

In combinatorial mathematics and theoretical computer science, a (classical) permutation pattern is a sub-permutation of a longer permutation.Any permutation may be written in one-line notation as a sequence of entries representing the result of applying the permutation to the sequence 123...; for instance the sequence 213 represents the permutation on three elements that swaps elements 1 and 2.
Similarly to a stack of plates, adding or removing is only practical at the top. Simple representation of a stack runtime with push and pop operations.. In computer science, a stack is an abstract data type that serves as a collection of elements with two main operations:
