[C++] stack, queue and deque

Introduction to stack Stack is a container adapter that is specially used in contexts with last-in-first-out operations. Its deletion can only insert and extract elements from one end of the container. Stack is implemented as a container adapter. A container adapter encapsulates a specific class as its underlying container and provides a set of specific […]

STL deque(C++)

1, basic concepts Function: Double-ended array, you can perform insertion and deletion operations on the head end. The difference between deuqe and vector: Vector has low efficiency for insertion and deletion of headers. The larger the amount of data, the lower the efficiency; Relatively speaking, deque inserts and deletes headers faster than vector; The speed […]

C++STL universal container—–>deque

The full name of deque is double-ended queue. It supports insertion and deletion operations from both ends of the queue, so it can be regarded as a combination of stack and queue. deque dual-port container, sequential storage, random access iterator Header file: #include Deque traversal void disp(deque<int> d)//Traversal//Forward iterator, and reverse iterator { deque<int>::iterator i […]

Using array to implement deque ArrayDeque

A queue is a special linear table that is special in that it only allows deletion operations at the front end of the table (front) and insertion operations at the back end (rear) of the table. Like a stack, a queue is a linear list with restricted operations. The end that performs the insertion operation […]
