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...
Java C C++ # Queue implementation in Python class Queue(): def __init__(self, k): self.k = k self.queue = [None] * k self.head = self.tail = -1 # Insert an element into the queue def enqueue(self, data): if (self.tail == self.k - 1): print("The queue is full\n"...
Stack作为最基本的数据结构,在JDK代码中,也有它的实现,java.util.Stack类是继承了Vector类,来实现了栈的基本功能。 1.栈的基本原理 栈(Stack)是限定仅在表尾进行插入或者删除操作的线性表。因此,对于栈来说,表尾端有特殊含义,成为栈顶,表头称之为栈底。......

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?
进行插入操作的端称为队尾,进行删除操作的端称为队头。 队列中最先插入的元素也将最先被删除,对应的最后插入的元素将最后被删除。因此队列又称为“先进先出”(FIFO—first in first out)的线性表,与栈(FILO-first in last out)刚好相反。 2.java中的队列...
