The following &quot;score&quot; function will be used calculate the <br /># score of a single roll of the dice. <br /># <br /># A greed roll is scored as follows: <br /># <br /># * A set of three ones is 1000 points <br /># <br /># * A set of three numbers (other than ones) is worth 100 times the <br /># number. (e.g. three fives is 500 points). <br /># <br /># * A one (that is not part of a set of three) is worth 100 points. <br /># <br /># * A five (that is not part of a set of three) is worth 50 points. <br /># <br /># * Everything else is worth 0 points. <br /># <br /># <br /># Examples: <br /># <br /># score([1,1,1,5,1]) =&gt; 1150 points <br /># score([2,3,4,6,2]) =&gt; 0 points <br /># score([3,4,5,3,3]) =&gt; 350 points <br /># score([1,5,1,2,4]) =&gt; 250 points</p> <pre>def score(dice) count = [0,0,0,0,0,0] dice.each { |i| count[0] += 1 if i == 1 count[1] += 1 if i == 2 count[2] += 1 if i == 3 count[3] += 1 if i == 4 count[4] += 1 if i == 5 count[5] += 1 if i == 6 } sum = 0 unless dice == [] if count[0] &lt; 3 sum += count[0] * 100 elsif count[0] == 3 sum += 1000 elsif count[0] &gt; 3 sum = 1000 + (count[0] -3) * 100 end (1..5).each { |i| if count[i] == 3 sum += (i+1) * 100 end } if count[4] &lt; 3 sum += count[4] * 50 elsif count[4] &gt; 3 sum = 500 + (count[4] -3) * 50 end end return sum end</pre> websymphony.blogspot.com amitgaur84@gmail.com
