A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion)
Explain The merits of using a deque to implement a stack in data structure
deque
The time complexity of deque operations in data structures is O(1), which means they have constant time complexity.
The C++ STL (Standard Template Library) provides a std::deque template specifically for this purpose: std::deque<int> deq {}; // default construct an empty deque of type int deq.push_back (42); // deq = {42} deq.push_front (0); // deq = {0, 42} deq.push_back (100); // deq = {0, 42, 100} deq.pop_front (); // deq = {42, 100} deq.pop_back (); // deq = {42} As with all other STL containers, any type or class that can be copy or move constructed can be placed in a std::deque, including other STL containers (even std::deque itself).
#include<deque> std::deque<int> deq; deq.push_back (42); deq.pop_back (); deq.push_front (0); deq.pop_front ();

A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion). So when we need to insert or delete at both end we need deque.
