*In a team sailing competition, six races are sailed and, in each race, each boat is allocated points for the position in which it finishes, the most points going to the winner.*

*To calculate the final score for a boat, only its five best races are considered; the worst score for each boat is ignored.*

*A team consists of four boats, but only the three highest scoring boats are counted in the final total for the team.*

*Design a program, to process the points scores by each boat in a team and calculate the total score for the team.*

PHP:

`<?`

` // i'm going to assume they are playing one other team, so the possible scores are`

` // first (3 points), second (2 points), third (1 points) and everything else is nothing`

` $scores = array(3, 2, 1, 0, 0, 0, 0, 0);`

` `

` // simulate six races`

` for ($a = 0; $a < 6; $a++)`

` {`

` // randomize positions`

` shuffle($scores);`

` // get the score for each boat`

` for ($b = 0; $b < 4; $b++)`

` // store the score`

` $boats[$b][$a] = $scores[$b];`

` }`

` `

` // loop through each boat`

` for ($n = 0; $n < 4; $n++)`

` // and display it's score`

` echo 'Boat ' . ($n+1) . ' race scores: ' . implode(', ', $boats[$n]) . '<br/>';`

` `

` // loop through each boat`

` for ($n = 0; $n < 4; $n++)`

` {`

` // sort its scores`

` rsort($boats[$n]);`

` // take off the lowest`

` array_pop($boats[$n]);`

` }`

` `

` echo '<br/>';`

` // loop through each boat`

` for ($n = 0; $n < 4; $n++)`

` {`

` // it's final score is it's top five scores added together`

` $boats[$n] = array_sum($boats[$n]);`

` // show the final boat score`

` echo 'Boat ' . ($n+1) . ' final score: ' . $boats[$n] . '<br/>';`

` }`

` `

` // sort the scores for all the boats`

` rsort($boats);`

` // take off the lowest`

` array_pop($boats);`

` `

` // add up all the remaining scores`

` echo '<br/>Team score: ' . array_sum($boats);`

` `

`?>`

Which produces:

Boat 1 race scores: 0, 0, 0, 0, 0, 2

Boat 2 race scores: 0, 0, 0, 1, 1, 0

Boat 3 race scores: 0, 1, 0, 0, 0, 3

Boat 4 race scores: 2, 2, 0, 2, 0, 0

Boat 1 final score: 2

Boat 2 final score: 2

Boat 3 final score: 4

Boat 4 final score: 6

Team score: 12
