The complexity of enqueue and dequeue operations in a queue using an array isO(1). If you usepop(N)in python code, then the complexity might beO(n)depending on the position of the item to be popped. Applications of Queue CPU scheduling, Disk Scheduling ...
The most common queue implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Circular Queue implementation in PythonclassMyCircularQueue():def__init__(self, k):self.k = k self.queue = [None] * k self.head = self.tail =-1# Insert an element...

Q5. Can a queue be implemented using an array? Yes, a queue can be implemented using an array. In such an implementation, the rear of the queue is associated with the end of the array, and the front is associated with the beginning. However, it is important to handle cases of overflow...
入队:容量够,放在数组_tail标处,同时 _tail = (_tail + 1) % _array.Length,可能导致_head > _tail,后面如需扩容时分两步,先先复制头到数组size-1标,再复制数组0标到尾;容量不够,先扩容 // Adds obj to the tail of the queue. //
In these post we learned about the usages of a priority queue and how to implement it with an array+sorting and using array-based heap. We also explored it’s time complexity for each implementation so we can verify that the heap implementation is more efficient.Now...

无锁栈(lock-free stack)无锁数据结构意味着线程可以并发地访问数据结构而不出错。例如,一个无锁栈能同时允许一个线程压入数据,另一个线程弹出数据。不仅如此,当调度器中途挂起其中一个访问线程时,其他线程必…
