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...

1. Which data structures can be used for queue implementation? An array, stack, or linked list can be used to implement a queue. Using an Array is the simplest way to implement a queue. 2. Which operation is used in the queue implementation? A queue is an object used to manipulate an...
Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
ConcurrentLinkedQueue() // 创建一个最初包含给定 collection 元素的 ConcurrentLinkedQueue,按照此 collection 迭代器的遍历顺序来添加元素。 ConcurrentLinkedQueue(Collection<? extends E> c) // 将指定元素插入此队列的尾部。 boolean add(E e) // 如果此队列包含指定元素,则返回 true。
Dequeue:Dequeue is known as double ended queue. In dequeue, the elements can be inserted or removed from both of the ends. Due to this property, dequeue may not follow the first in first out property. Queue implementation using Array: ...
concurrency control. However, thebulkCollection operationsaddAll,containsAll,retainAllandremoveAllarenotnecessarily performed atomically unless specified otherwise in an implementation. So it is possible, for example, foraddAll(c)to fail (throwing an exception) after adding only some of the elements inc...
