Consecutive Available Seats
Moderate
Asked in company
Several friends at a cinema ticket office would like to reserve consecutive available seats.
Can you help to query all the consecutive available seats order by the seat_id using the following cinema table?
| seat_id | free |
|------- |------|
| 1 | 1 |
| 2 | 0 |
| 3 | 1 |
| 4 | 1 |
| 6 | 1 |
Your query should return the following result for the sample case above.
| seat_id |
|---------|
| 3 |
| 4 |
Note:
The seat_id is an auto increment int, and free is bool ('1' means free, and '0' means occupied.).
Consecutive available seats are more than 2(inclusive) seats consecutively available.
