    -------------------------------------------------------------------------------------
    Masalah :
    Write a program that prompts the user to enter the day number of a week and hours 
    passed, and displays the day and remaining hours. For example, if the user entered 
    day number 1 and hours passed 20, the program should display Today is Sunday and 
    Remaining Hours: 4. If the user entered day number 7 and hours passed 2, the program 
    should display Today is Saturday and Remaining Hours 22.
