I decided to implement it myself without using a semaphore. Here is my first (incorrect) attempt of implementing a blocking queue with one producer and one consumer: #include <iostream> #include <mutex> #include <condition_variable> #include <thread> #include <queue> template <typename...
// "static void main" must be defined in a public class.publicclassMain{publicstaticvoidmain(String[] args){// 1. Initialize a queue.Queue<Integer> q =newLinkedList();// 2. Get the first element - return null if queue is empty.System.out.println("The first element is: "+ q.peek...
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 stack def create_stack(): stack = [] return stack # Creating an empty stack def check_empty(stack): return len(stack) == 0...
Double Stack Using Class Here, we willimplement a double-stack using class; we can implement two stacks inside a single array using class. Double Stack Implementation Using Class in C# The source code toimplement a Double Stack using classis given below. The given program is compiled and execut...

typically, you can only view the top element of a stack, which is the last item that was added. however, depending on the implementation and the language, there may be ways to view all the elements in the stack using debugging tools or by converting the stack to another data structure. ...
Learn how to implement Stack data structure in Java using a simple Array and using Stack class in Java with complete code examples and functions like pop, push.
