# Greed is a dice game where you roll up to five dice to accumulate
|
||
|
# points. The following "score" function will be used calculate the
|
||
|
# score of a single roll of the dice.
|
||
|
#
|
||
|
# A greed roll is scored as follows:
|
||
|
#
|
||
|
# * A set of three ones is 1000 points
|
||
|
#
|
||
|
# * A set of three numbers (other than ones) is worth 100 times the
|
||
|
# number. (e.g. three fives is 500 points).
|
||
|
#
|
||
|
# * A one (that is not part of a set of three) is worth 100 points.
|
||
|
#
|
||
|
# * A five (that is not part of a set of three) is worth 50 points.
|
||
|
#
|
||
|
# * Everything else is worth 0 points.
|
||
|
#
|
||
|
#
|
||
|
# Examples:
|
||
|
#
|
||
|
# score([1,1,1,5,1]) => 1150 points
|
||
|
# score([2,3,4,6,2]) => 0 points
|
||
|
# score([3,4,5,3,3]) => 350 points
|
||
|
# score([1,5,1,2,4]) => 250 points
|
||
|
#
|
||
|
# More scoring examples are given in the tests below:
|
||
|
#
|
||
|
# Your goal is to write the score method.
