publicvoidpush(intx) { while(!stack.isEmpty()){ aux.push(stack.pop()); } stack.push(x); while(!aux.isEmpty()){ stack.push(aux.pop()); } } // Removes the element from in front of queue. publicvoidpop() { stack.pop(); } // Get the front element. publicintpeek() { retu...
Implementing Queue using stack 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). ...
AfterREARreaches the last index, if we can store extra elements in the empty spaces (0 and 1), we can make use of the empty spaces. This is implemented by a modified queue called thecircular queue. Complexity Analysis The complexity of enqueue and dequeue operations in a queue using an ...
In this post , we will see how to implement Queue using Array in java. Queue is abstract data type which demonstrates First in first out (FIFO) behavior. We will implement same behavior using Array. Although java provides implementation for all abstract data types such as Stack, Queue and ...
Implementation of a stack using two queuesLikewise, a queue can be implemented with two stacks, a stack can also be implemented using two queues. The basic idea is to perform stack ADT operations using the two queues.So, we need to implement push(),pop() using DeQueue(), EnQueue() ...
Operation on Queue Basic operations: C++ implementation This article is about queue implementation using array in C++. Queue as an Abstract data Type Queue is an ordered data structure to store datatypes in FIFO (First in First Out) order. That means the element which enters first is first to...
Working of Stack Data Structure Stack Implementations in Python, Java, C, and C++ The most common stack implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Stack implementation in python# Creating a stackdefcreate_stack():stack = []returnstack# Cr...

1. How would you implement a stack in C using an array? Here is an example implementation of a stack using an array in C : #define MAX_SIZE 100 int stack[MAX_SIZE]; int top = -1; void push(int item) { if (top == MAX_SIZE - 1) { printf("Stack Overflow"); return; } top...
The following program in Java provides a demonstration of all the above BST operation using the same tree used in illustration as an example. class BST_class { //node class that defines BST node class Node { int key; Node left, right; ...
