/* We need to transfer data from a certain source to a consumer. The source provides data in small batches (~tens of records), while the consumer works more efficiently with larger batches (~thousands of records). A real-world example is transferring data from Kafka queues to a Clickhouse database. Source: - Conditionally infinite. - The source never returns more than MaxItems records per call to Next. - During a single "session" (one call to the Pipe function), the source returns new data on each Next call. - However, after a restart, the source resumes from the last "confirmed" position, set by a cookie. Therefore, *each* cookie value returned by Next, after data is saved in the receiver, must be fixed with a Commit call, strictly in the same order they were returned by Next. Receiver: - Cannot process more than MaxItems at once. The task is to implement the function func Pipe(p Producer, c Consumer) error which reads data from the source, groups it into a buffer of size not more than MaxItems, and saves it to the receiver, then commits the progress in the source. */ const MaxItems = 9999 // Producer interface // Next returns: // - batch of items to be processed // - cookie to be committed when processing is done // - error // Commit is used to mark data batch as processed // type Producer interface { Next() (items []any, cookie int, err error) Commit(cookie int) error } type Consumer interface { Process(items []any) error } func Pipe(p Producer, c Consumer) error { // TODO }

""" Seats in a cinema are arranged in a single row. A newly arrived viewer chooses a seat to sit as far as possible from others. That is, the distance from the seat they choose to the nearest viewer should be maximized. It is guaranteed that there are always free seats and at least one viewer is already seated. Write a function that, given a row of seats (an array of zeros and ones), returns the distance (number of gaps between chairs) from the chosen seat to the nearest viewer. [1, 0, 0, 0, 1] -> 2 [1, 0, 1, 0, 0, 1, 0, 0, 0, 1] -> 2 [1, 0, 1, 0] -> 1 """ func maxPlaces(arr []int) int { }
