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 q

Priority Queue in Data Structures - Learn about Priority Queue data structure, its operations, applications, and implementation techniques. Discover how to efficiently manage data with priority.
Algorithm for deletion of an element in the priority queue (max-heap) If nodeToBeDeleted is the leafNode remove the node Else swap nodeToBeDeleted with the lastLeafNode remove noteToBeDeleted heapify the array For Min Heap, the above algorithm is modified so that the bothchildNodesare smaller...
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: ...

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...

The algorithm to insert an element in a heap is as follows:Insert the element into the next empty position (tail). From that position, “bubble up” the element to keep the min-heap invariant “parent should be smaller than any children” (the opposite if max-heap). If the invariant ...
