Personalized Greeting Generator

You are given a customer's name and a time of day. Your task is to generate a personalized greeting message in the format Good <Time> <Name>, where <Time> is replaced by one of the valid time periods: morning, afternoon, evening, or night.

If the provided time does not match any of the valid time periods, output the exact error message: Invalid time of day. Must be one of 'morning', 'afternoon', 'evening', 'night'.

The solution should read input from stdin and produce output to stdout.

inputFormat

The input consists of two lines:

• The first line contains the customer's name (a non-empty string).
• The second line contains the time of day as a string. Valid values are: morning, afternoon, evening, and night.

outputFormat

If the provided time is valid, output a single line containing the greeting message in the format Good <Time> <Name>.

If the time is invalid, output the error message exactly as: Invalid time of day. Must be one of 'morning', 'afternoon', 'evening', 'night'.
