### Instruction:
What is the minimum amount of points a player needs to score to win a badminton match?

### Input:
In Badminton, each game is played to 21 points, with players scoring a point whenever they win a rally regardless of whether they served (this differs from the old system where players could only win a point on their serve and each game was played to 15 points). A match is the best of three games.

If the score ties at 20–20, then the game continues until one side gains a two-point lead (such as 24–22), except when there is a tie at 29–29, in which the game goes to a golden point of 30. Whoever scores this point wins the game.

### Response:
The minimum number of points needed to win a match of badminton is 42. In such a match only 2 games are played with the winning player scoring 21 points in each of them.
