The local high school baseball team, the Randal Schwartz High School Phoenixes, will be playing a series of games against their rivals, the Richard M. Nixon Memorial High School Growlin' Fungus. The series lasts at most five games, and ends when one team has won three games. You want to bet \$80 on the Phoenixes to win the series, but your bookie will only take bets on individual games. (The bookie pays even money on all bets.) A mathematically-inclined friend solves the problem for you, giving you the following instructions: Bet \$30 on each of the first two games. Bet \$20 on the third game if either team has won both of the first two games, \$40 otherwise. Bet \$40 on the fourth game, if there is one. Bet \$80 on the fifth game, if there is one. At the end of the series, you will be ahead by exactly \$80 if the Fightin' Quakers have won the series, and behind by exactly \$80 if the Sewer Fungus have won. We could summarize the instructions in a table like this: If the game score is: 0 to 0, bet \$30 1 to 0, bet 30 1 to 1, bet 40 2 to 0, bet 20 2 to 1, bet 40 2 to 2, bet 80 Write a function which calculates the appropriate bet for any such contest, given the total amount you want to risk on the series, the length of the series, and the current game score. For example, bet(80, 5, 2, 1) should return 40, because if you want to risk \$80 on a 5-game series, and one team is presently ahead 2 games to 1, you should bet \$40. Similarly bet(1000, 7, 2, 1) should return 375. (That is, if you're trying to bet \$1000 on the current World Series baseball match, you need to bet \$375 on the outcome of tonight's game. If you started with \$1000, and followed this function's advice, you'd have \$625 left if you had been betting on the Giants and \$1375 if you had been betting on the Angels. For people living in places where the World Series is irrelevant: the match is a best-four-of-seven series of games; at present, the Anaheim Angels are beating the San Francisco Giants two games to one, with the fourth game scheduled for tonight.) ---------------------------------------------------------------- The same notes as last week; read them *all* if you didn't read them last week: * I'll post an example solution here on Monday. * perl-qotw will only carry the quizzes and solutions.
