class TimeSpanDemo
{
    //Entry point of Program
    static public void Main()
    {
        TimeSpan timespan1 = new TimeSpan(2, 0, 0);
        TimeSpan timespan2 = new TimeSpan(0, 90, 0);
        TimeSpan timespan3 = new TimeSpan(2, 0, 0);

        if (timespan1 != timespan2)
            Console.WriteLine("Both instances are not equal");
        else
            Console.WriteLine("Both instances are equal");

        if (timespan1 != timespan3)
            Console.WriteLine("Both instances are not equal");
        else
            Console.WriteLine("Both instances are equal");
    }
}
