What is Queue in Python? A queue is an abstract data type used for storing and managing data in a specific order. It has a rear (where elements are added) and a front (where elements are removed). Queues can be implemented using arrays or linked lists and support multi-producer, multi...
Code explanation to implementation of priority queue using linked list In the Code below there are four parts. First three function to implement three different operations like Insert a node, delete a node and display the list. The Fourth part is the main function, in that a do while loop i...

Queue用法python python queue函数 队列queue 多应用在多线程应用中,多线程访问共享变量。对于多线程而言,访问共享变量时,队列queue是线程安全的。从queue队列的具体实现中,可以看出queue使用了1个线程互斥锁(pthread.Lock()),以及3个条件标量(pthread.condition()),来保证了线程安全。queue队列的互斥锁和条件变量,...

阻塞queue: LinkedBlockingQueue:使用单链表储存元素,默认情况下无界,但也可以规定队列大小,底层主要通过reentrantLock和atomicInteger来保证线程安全,用condition的await 和signal实现阻塞。这里put和take使用了不同的锁,这样在高并发情况下会有更好的性能,这里需要注意一下的是await和signal都需要在上锁的情况下执行,因为....
