- Given a list of schedules, provide a list of times that are available for a meeting.
|
|
|
|
```
|
|
[
|
|
[[4,5], [6,10], [12,14]],
|
|
[[4,5], [5,9], [13,16]],
|
|
[[11,14]]
|
|
]
|
|
|
|
Example Output:
|
|
[[0,4], [11,12], [16,23]]
|
|
```

|
- You have a number of meetings (with their start and end times). You need to schedule them using the minimum number of rooms. Return the list of meetings in every room.
|
|
- Interval ranges:
|
|
- Given 2 interval ranges, create a function to tell me if these ranges intersect. Both start and end are inclusive: `[start, end]`
|
|
- E.g. `[1, 4]` and `[5, 6]` => `false`
|
|
- E.g. `[1, 4]` and `[3, 6]` => `true`
|
|
- Given 2 interval ranges that intersect, now create a function to merge the 2 ranges into a single continuous range.
|
|
- E.g. `[1, 4]` and `[3, 6]` => `[1, 6]`
|
|
- Now create a function that takes a group of unsorted, unorganized intervals, merge any intervals that intersect and sort them. The result should be a group of sorted, non-intersecting intervals.
|
|
- Now create a function to merge a new interval into a group of sorted, non-intersecting intervals. After the merge, all intervals should remain
|
|
non-intersecting.
|
|
- Given a list of meeting times, check if any of them overlap. The follow-up question is to return the minimum number of rooms required to accommodate all the meetings.

- If you have a list of intervals, how would you merge them?
|
|
- E.g. `[1, 3], [8, 11], [2, 6]` => `[1, 6], [8-11]`
