Attendance Management System Simulation

You are required to implement an attendance management system. The system initially contains two attendance records:

• Employee 1: Date = 2023-10-11, Time = 09:00
• Employee 2: Date = 2023-10-11, Time = 09:05

The system supports the following commands (each command is provided on a separate line after the first input line which contains an integer T indicating the number of commands):p>

• MARK employee_id date time: Add a new attendance record with the given employee_id, date, and time.
• VIEW employee_id: Display all attendance records for the given employee_id in descending order of date (i.e. records with later dates are shown first). If no records exist, output None.
• EDIT employee_id date new_time admin_flag: Update the time of the attendance record for the given employee_id and date. If admin_flag is true, then update the record and output "Record Updated" if the record exists; if no matching record is found, output "Record Not Found". If admin_flag is false, output "Access Denied" and do not update any record.
• FILTER start_date end_date: Print all attendance records whose date lies within the inclusive range from start_date to end_date in ascending order of date. If no records are found, output None.

Dates are provided in the format \(YYYY-MM-DD\) (i.e. \(\text{\textbf{\(YYYY-MM-DD\)}}\)).

inputFormat

The first line contains an integer T, denoting the number of commands. Each of the next T lines contains a command in one of the following formats:

• MARK employee_id date time
• VIEW employee_id
• EDIT employee_id date new_time admin_flag where admin_flag is either true or false
• FILTER start_date end_date

All inputs are taken from standard input (stdin).

outputFormat

For each command that requires an output:

• VIEW: Print each matching record on a new line in the format: employee_id date time. If no record exists for the given employee, print None.
• EDIT: Print one line with the result message: either "Record Updated", "Record Not Found", or "Access Denied".
• FILTER: Print each matching record on a new line in the format: employee_id date time in ascending order of date. If no records match, print None.
• MARK: Does not produce any output.

All outputs should be printed to standard output (stdout).
