What happens if a player is dribbling steps out of bounds the ball still in bounds then steps back in bounds and continues dribbling again?

If a player dribbling the ball steps out of bounds while the ball is still in bounds, they lose their status as a player in bounds. When they step back in bounds, they cannot legally continue dribbling until they re-establish themselves in bounds. Specifically, they must ensure both feet are in bounds before they can resume dribbling. If they continue dribbling without re-establishing their position, it results in a turnover.
