circular queue java

The basic structure of the loop queue is as follows:The front property represents the team header, and the rear property represents the tail of the team.When the team is empty: Q.rear and Q.front are all 0, the rest of the time Q.rear point to the successor of the tail, Q.front points to the head of the team.When inserting elements at the end of a queue, Q.rear + 1, when deleting a team header element, Q.fr

Queue everyone seen a lot, the form is also relatively simple, is a special list, its enqueue, dequeue operation equivalent to the list of addlast, Removefirst operation. For the implementation of the linked list, you can view my other blog post-"linkedlist--linked list". The following is only a slightly more complex scenario-the loop queue.Loop queue is to use a loop array to implement the

/* * April 17, 2015 09:07:17 * Objective: To implement the cyclic queue (sequential storage structure), I would like to implement the queue before the implementation of the queued order storage, but this algorithm has a great disadvantage * first will cause false overflow phenomenon *//* * Solve the problem of queue, is how to judge Whether the

Suppose a circular single linked list is used to represent the queue, and only one pointer is set to point to the rear node, but without the head pointer, an algorithm is designed to initialize, join, team, and determine whether the queue is empty.Method One: Use the cycle single linked list without the lead node.1.1 Team Empty Condition Rear==null1.2 Join the te

Some SCM serial port does not have FIFO, or can be assigned to the FIFO size is very limited, if the program needs to send a large packet to the peripheral, it takes a long time, in order to solve the application and peripherals hardware read and write synchronization problem, it is necessary to realize the circular FIFO. #include "stdafx.h"#include #include using namespace Std; #define Error_full_w-1#define Error_empty_r-2 #define TRUE 0#define FULL
