6. Write a program to create a generic queue/stack and perform insert, delete
and display operations on it.

CODE >>

using System;
using System.Collections.Generic;

public class GenericDataStructure
{
    public static void Main()
    {
        // Generic Queue
        Queue<string> queue = new Queue<string>();
        queue.Enqueue("Apple");
        queue.Enqueue("Banana");
        queue.Enqueue("Cherry");

        Console.WriteLine("Generic Queue Operations:");
        Display(queue);
        Console.WriteLine("Dequeue: " + queue.Dequeue());
        Display(queue);

        // Generic Stack
        Stack<string> stack = new Stack<string>();
        stack.Push("Apple");
        stack.Push("Banana");
        stack.Push("Cherry");

        Console.WriteLine("\nGeneric Stack Operations:");
        Display(stack);
        Console.WriteLine("Pop: " + stack.Pop());
        Display(stack);
    }

    private static void Display<T>(IEnumerable<T> collection)
    {
        Console.WriteLine("Current Collection:");
        foreach (T item in collection)
        {
            Console.Write(item + " ");
        }
        Console.WriteLine("\n");
    }
}

7. Write a program to create a nongeneric queue/stack and perform insert,
delete and display operations on it.


CODE >>

using System;
using System.Collections;

public class NonGenericDataStructure
{
    public static void Main()
    {
        // Non-Generic Queue
        Queue queue = new Queue();
        queue.Enqueue("Apple");
        queue.Enqueue("Banana");
        queue.Enqueue("Cherry");

        Console.WriteLine("Non-Generic Queue Operations:");
        Display(queue);
        Console.WriteLine("Dequeue: " + queue.Dequeue());
        Display(queue);

        // Non-Generic Stack
        Stack stack = new Stack();
        stack.Push("Apple");
        stack.Push("Banana");
        stack.Push("Cherry");

        Console.WriteLine("\nNon-Generic Stack Operations:");
        Display(stack);
        Console.WriteLine("Pop: " + stack.Pop());
        Display(stack);
    }

    private static void Display(IEnumerable collection)
    {
        Console.WriteLine("Current Collection:");
        foreach (var item in collection)
        {
            Console.Write(item + " ");
        }
        Console.WriteLine("\n");
    }
}
