Tennis is a racket sport that is played by two opposing players on S sets. Each set consists of at least Kgames. A set is won by a player if that player wins at least K games and at least 2 games more than theopponent. Once a set is won, the set is ended and the match continues to a new set (if any) where bothplayers start from 0 game won for that new set.For example, let K = 6, then a set can be ended with any of the following.• P1 (Player 1) wins 6 games while P2 (Player 2) wins 3 games → P1 wins the set.• P1 wins 7 games while P2 wins 9 games → P2 wins the set.On the other hand, a set cannot be ended with any of the following.• P1 wins 6 games while P2 wins 5 games → no player wins at least 2 games more than the opponent.• P1 wins 0 game while P2 wins 5 games → no player wins K = 6 games.• P1 wins 7 games while P2 wins 0 games → the set is already ended when P1 won the first 6 games.• P1 wins 8 games while P2 wins 5 games → the set must already be ended before it reaches this…
