# 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.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
