The following sequence shows all bookings $($advance and walk$-$in$)$ within the system for a given night. When a table is not allocated, $0$ is used in place of a table number. Smith is assigned registration ID $22$ and is a walk$-$in$,$ so is not assigned a table number. Mason booked in advance and requested table $2.$ They are assigned reservation ID $23.$ Jones is also a walk$-$in and is assigned ID $24.$ They were also not assigned a table number. Nobody is currently assigned table $4.$ Note that the system does not record the party size.

$|$ Reservation ID $|$ Name $|$ Table $|$

$|$ :$-$: $|$ :$-|$ :$-$: $|$

$|22|$ Smith $|0|$

$|23|$ Mason $|2|$

$|24|$ Jones $|0|$

If the booking data were to be stored in an array of dicts $($instead of in a Python list$),$ explain and justify the assumptions you would need to make. Explain the processes you would need to go through to be able to add a new advance booking for a patron as well as a walk$-$in booking. Refer to the table above to illustrate your points.
