Container adapter -- queue, stack, priority_queue

What is an adapter adapters play the role of bearing and converter in the flexible combination and application function of STL components. The concept of adapter is actually a design pattern. In the design pattern, the definition of adapter style is as follows: convert one class interface into another class interface, so that classes that ...

Java programming thought notes 11 - Chapter 11: holding objects

11 holding object Usually, the program always creates new objects according to certain conditions known at runtime. There is no need to define the number of objects to be created in advance. You can create any number of objects as needed. Array must implement the specified number, so it is constrained. Java provides container classes to sol ...

Queue of data structure

Queue introduction Queue is a special linear table, which only allows deletion at the front of the table and insertion at the back of the table. The position where the deletion operation is performed is called the opposite head, and the position where the insertion operation is performed is called the end of the queue. characteristic FIFO first ...

Data structure - simulate queue with Stack & simulate stack with queue

Two stacks S1 and S2 are used to simulate a queue. Two stacks S1 and S2 are used to simulate a queue. When an element needs to be inserted into the queue, S1 is used to store the input element, that is, S1 performs the stack operation. When it is necessary to get out of the queue, the stack operation is performed on S2. Since the order of t ...
