        //Multithreading Coding Exercise

        //Problem Statement

        //Write a C# program that demonstrates the use of multithreading to improve performance. The program should:

​

        //Create three threads that perform different tasks concurrently:

        //Thread 1: Prints numbers from 1 to 10 with a 500ms delay.

        //Thread 2: Prints the square of numbers from 1 to 10 with a 700ms delay.

        //Thread 3: Prints the cube of numbers from 1 to 10 with a 900ms delay.

        //Use the Thread class to create and manage threads.

        //Ensure all threads complete execution before the program exits.

        // 1. Create threads

        Task numbers500 = Task.Run(() => PrintNumbers(500));

        Task numbers700 = Task.Run(() => PrintNumbers(700));

        Task numbers900 = Task.Run(() => PrintNumbers(900));

        // 2. Start threads

        // 3. Wait for all threads to complete     

        Task.WaitAll(numbers500, numbers700, numbers900);           

    }

    public static void PrintNumbers(int delay){

        for (int i = 1; i <= 10; i++){

            Console.WriteLine(i);

            Thread.Sleep(delay);

        }

    }
