Parking Booking Validator

A visitor car park booking system requires the user to input the day they want to book within a two-week period (days 1 to 14).

Write a program that repeatedly takes an integer input. If the input is outside the valid range (1 to 14 inclusive), output "Invalid day" and ask again. Once a valid day is entered, output "Accepted: " followed by the day number and terminate.

Input: A sequence of integers. Output: "Invalid day" for out-of-range inputs, then "Accepted: X" for the valid input.

Example:

Input:  0
        15
        14
Output: Invalid day
        Invalid day
        Accepted: 14
