Implement the classes and methods defined below :-
1. A class named SeatReservation.

Name :-
m

Methods :-
Name :-
string reserve(int r, int k)
Functionality :-

If the seats are available, the function should return a string with the first seat number of the booked seat in the format "Booked with seat number s" where s is the number of the first seat available in the rth row. If it is not possible, return "Seats not available" and do not reserve a seat.
Example :-
n=2,m=3
q=2
first query: (1, 3)
second query (2, 4)
The theater has 2 rows of 3 seats.
The first request is for 3 seats in row 1. They are available, starting at seat 1. Return "Booked with seat number 1".
The second query is for 4 seats in row 2. Row 2 does not have 4 adjacent seats available. Return "Seats not available".
Requests are handled in the order received and allocations persist through the series of requests. A seat cannot be booked twice.
Constraints :-
• 1 ≤ n, m ≤ 10^5
• 1 ≤ q ≤ 10^4
• 1 ≤ r ≤ n
