Player from team A steals the ball at half court on a pass from team B, as the team A player is then dribbling the ball towards his basket and while he is very close to his sideline he looses posession of the ball and his momentum carries him out of bounds, then re-enters the court and is the first to touch the ball and regains his dribble and goes in for a layup.

Was the team A player allowed to leave the court, be the last one to touch the ball, go out of bounds, and then return to the court and be the first to touch the ball? Is this a violation or a legal play?
