A queue can be implanted using stack also. We need two stacks for implementation. The basic idea behind the implementation is to implement the queue operations (enqueue, dequeue) with stack operations (push, pop). Implementation: Let s1 and s2 be the two stacks used for implanting the queue...
In this paper, we design and implement a quantifiable stack (QStack) and queue (QQueue) and present results showing that quantifiable data structures are highly scalable through use of relaxed semantics, an explicit implementation trade-off permitted by quantifiability. We present a technique for ...
enQueue(Type_t data): It inserts data of datatype Type_t to the queue Type_t deQueue(): Removes the first element(at front end) from queue and returns it Other operations: Type_t queue_front(): Returns front element bool isEmpty(): returns true if queue is empty, else returns false...

Lightweight implementation of queues in TypeScript. You can use it to improve the performance of your node or browser applications built with JavaScript/TypeScript This package contains six different implementations of queue: Array queue (new ArrayQueue()) Array stack queue (new ArrayStackQueue())...
Although java provides implementation for all abstract data types such as Stack, Queue and LinkedList but it is always good idea to understand basic data structures and implement them yourself. Please note that Array implementation of Queue is not dynamic in nature. There are two most important op...
如果设置,这个Activity会成为历史stack中一个新Task的开始。一个Task(从启动它的Activity到下一个Task中的 Activity)定义了用户可以迁移的Activity原子组。Task可以移动到前台和后台;在某个特定Task中的所有Activity总是保持相同的次序。 这个标志一般用于呈现“启动”类型的行为:它们提供用户一系列可以单独完成的事情,与...
Enqueue: This operation is used to Insert an element at the rear end of the queue. Dequeue: This operation is used to remove and return an element from the front end of the queue. isEmpty(): This operation is used to check whether the queue is empty or not. It returns bool value, ...
