• Prompt and read in two DateTime values and a string value from the user. The string value should contain some bracketed [ ] text, at least one \"^\" character, and a mixture of upper and lower case letters. Validate the DateTime values entered by the user are valid; if not, display a message and end the program; if they are valid, continue.

• Calculate and output:

• Whether the first date is before the second or not
• The absolute difference in minutes between the two dates (to 2 decimals positions, with thousands separators)
• The user string, after converting it entirely to upper case, removing the substring between the first occurrence of [ and ] characters (including the brackets), and replacing each \"^\" character with \"LSU\".
