Each team during a game of football is able to make up to three substitutions. In association football a substitute is a player brought onto the field for an existing player, generally because they are tired, fatigued or under performing. A player may only be substituted when the play stops and the referee gives the signal to notify they are allowing this to happen. The player must only enter the field at the half way line and wait for their team-mate to leave the football pitch. The player who has left the field is not allowed to return to the pitch for the duration of the match. . Already seen program statement types. :. rules: p(X) :- q(X,Y), r(.
