//Problem 10.   * Beer Time
//A beer time is after 1:00 PM and before 3:00 AM. Write a program that enters a time in format “hh:mm tt” (an hour in range [01...12], a minute in range [00…59] and AM / PM designator) and prints “beer time” or “non-beer time” according to the definition above or “invalid time” if the time cannot be parsed. Note that you may need to learn how to parse dates and times.

using System;
using System.Globalization;

class BeerTime
{
    static void Main()
    {
        CultureInfo enUS = new CultureInfo("en-US");
        DateTime time;
        DateTime startTime = DateTime.Parse("1:00 PM");
        DateTime endTime = DateTime.Parse("3:00 AM");
        string dateString = Console.ReadLine();
        if (DateTime.TryParseExact(dateString, "h:mm tt", enUS, DateTimeStyles.None, out time))
        {
            if (time > startTime || time < endTime)
            {
                Console.WriteLine("beer time");
            }
            else
            {
                Console.WriteLine("non-beer time");
            }
        }
        else
        {
            Console.WriteLine("invalid time");
        }
    }
}
