We simply check for the rear pointer to reach at MAXSIZE to check that the queue is full because we are utilizing a single dimension array to create the queue. The algorithm will be different if we retain the queue as a circular linked list. The isfull() function’s algorithm − Algo...
self.top=0def__new__(self, depth, **kwargs):#return [0 for x in range(depth)]#If __new__() is invoked during object construction and it returns an instance or subclass of cls, then the new instance’s __init__() method will be invoked like __init__(self[, ...]), where...
1、队列的基本结构 队列(queue)是一种线性表,其限制是仅允许在表的一端进行插入,而在表的另一端进行删除,插入元素的一端称为队尾(rear),删除元素的一端称为队首(front)。从队列中删除元素称为离队或出队,元素出队后,其后续元素成为新的队首元素。队列的结构示意图,如下所示: 由于队列的插入和删除操作分别...

Queue is an abstract data type or a linear data structure or FIFO data structure. This tutorial will help you understand Queue data structure, its implementation and its application and usage in real world.

在《algorithm》书中提出了一个很有趣的情况,如果我们从N个元素中选出最大的M个元素,那么其时间复杂度是多少。 书中讨论了三种方法: 1)通过排序得出,但是我们可以很明确的明白如果N过大,这个方法需要消耗很长时间。 2)如果我们使用基础优先队列,我们在insert新元素的时候,和存在的五个元素进行比较,那么这个时间复...

This module provides an implementation of the heap queue algorithm, also known as the priority queue algorithm. Heaps are binary trees for which every parent node has a value less than or equal to any of its children. This implementation uses arrays for which $heap\left[k\right] \le heap\...
