Question

我正在写一个小猜谜游戏。我正在写一个点计算算法。

我写了以下内容，它有效。但我觉得我正在将程序背景带入Ruby，或者没有正确地利用Ruby。

经验丰富的Ruby程序员如何解决问题？您可以在TryRuby.com上测试代码（在浏览器解释器中复制和粘贴代码）。

# g = guesses
g = [{ id: 1, elmer: 5, roger: 7, outcome: "Roger Win" },{ id: 2, elmer: 5, roger: 1, outcome: "Elmer Win" },{ id: 3, elmer: 4, roger: 8, outcome: "Roger Win" }]
# r = actual results
r = [{ id: 1, elmer: 3, roger: 9, outcome: "Roger Win" },{ id: 2, elmer: 7, roger: 9, outcome: "Roger Win" },{ id: 3, elmer: 4, roger: 8, outcome: "Roger Win" }]
# points table
p = []    
# rules: correct outcome = 1 point, perfect match = 5 points.

# Loop over results.
r.each do |result|

  # Loop over guesses.
  g.each do |guess|

    # Make sure we compare corresponding ids.
    # So, compare result 1 to guess 1, r2 to g2, etc....
    if result[:id] == guess[:id]

      # Init a hash to store score
      score = {}

      # Did they guess the correct outcome?
      if result[:outcome] == guess[:outcome]

        # Correct outcome guessed! Make a score hash, give'em a point.
        score[:id]     = result[:id]  # game id
        score[:points] = 1            # point

        # Was it a perfect match?
        if result[:elmer] == guess[:elmer] && result[:roger] == guess[:roger]

          # Perfect match! Give them 4 points.
          # They already got 1 point for guessing the correct outcome.
          score[:points] += 4
        end
      end

      # Add the score to the points table
      p.push(score) unless score.empty?
    end
  end
end

这对你来说如何？

g.zip(r).collect do |guess, result|
  points = (guess == result) ? 5 : guess[:outcome] == result[:outcome] ? 1 : 0   
  {:id => guess[:id], :points => points} 
end

注意：这假定g和r按以下顺序排序：id;如果没有，你可以在这之前排序=）另外，我会定义：FULL_SCORE = 5和CORRECT_OUTCOME_SCORE = 1
