STABLE PUBLIC PREVIEW

Seat row

During a timed test, mark seats as taken and report the first free seat.

Question

Online assessment. A row of seats is numbered from 1. Implement take, which marks a free seat as taken and fails if that seat is already taken. Implement first free, which returns the lowest numbered free seat, or reports that the row is full. Then the test adds a second row and asks you to search the first row before the second. Write both functions and one example of a full row.

PRODUCT FEEDBACK

Was this practice useful?

Rate this surface from 1 to 5. A rating sends the score, an allowlisted feature key, and random event/device identifiers; when signed in, the server associates it with your account and tier. It sends no code, notes, prompt text, email, URL, IP-address field, or user-agent field.

Share privacy-safe automatic feature-use and browser performance measurements from this browser. Performance is counted by route family and mobile/desktop viewport class. Local code and workspace content are never included. Ratings are sent only when you press a rating button, independent of this setting. Share signed-in page and question time, visible Python or notebook coding-pane time, and selected practice actions for product improvement. The operator can review these by account and question. This is off by default. Code, typed text, and workspace content are excluded. Raw events are kept for up to 30 days.
