Most calendar applications provide some kind of "meet with" feature where the user can input a list of coworkers with whom they want to meet, and the calendar will output a list of times where all the coworkers are available.
For example, say that we want to schedule a meeting with Jane, John, and Mary on Monday.
- Jane is busy from 9am - 10am, 12pm - 1pm, and 4pm - 5pm.
- John is busy from 9:30am - 11:00am and 3pm - 4pm
- Mary is busy from 3:30pm - 5pm.
Based on that information, our calendar app should tell us that everyone is available:
- 11:00am - 12:00pm
- 1pm - 3pm
We can then schedule a meeting during any of those available times.
Given the data in events.json and users.json, build a script that displays available times
for a given set of users. For example, your script might be executed like this:
python availability.py Maggie,Joe,Jordan
and would output something like this:
2021-07-05 13:30 - 16:00
2021-07-05 17:00 - 19:00
2021-07-05 20:00 - 21:00
2021-07-06 14:30 - 15:00
2021-07-06 16:00 - 18:00
2021-07-06 19:00 - 19:30
2021-07-06 20:00 - 20:30
2021-07-07 14:00 - 15:00
2021-07-07 16:00 - 16:15
For the purposes of this exercise, you should restrict your search between 2021-07-05 and 2021-07-07,
which are the three days covered in the events.json file. You can also assume working hours between
13:00 and 21:00 UTC, which is 9-5 Eastern (don't worry about any time zone conversion, just work in
UTC). Optionally, you could make your program support configured working hours, but this is not necessary.
A list of users that our system is aware of. You can assume all the names are unique (in the real world, maybe they would be input as email addresses).
id: An integer unique to the user
name: The display name of the user - your program should accept these names as input.
A dataset of all events on the calendars of all our users.
id: An integer unique to the event
user_id: A foreign key reference to a user
start_time: The time the event begins
end_time: The time the event ends
- Please implement solution using Ruby
- Please provide instructions for execution of your program
- Please include a description of your approach to the problem, as well as any documentation about key parts of your code.
- You'll notice that all our events start and end on 15 minute blocks. However, this is not a strict requirement. Events may start or end on any minute (for example, you may have an event from 13:26 - 13:54).
