这样做更优雅的方式？

Question

我一直对自己说,一定有更好的方法,但我现在看不到它......想法？

i = 0; lose = 0; win = 0
while i < @array.size
  results = @array[i].results
  q = 0
  while q < results.size
    if results[q].to_i == 0 then
      lose += 1
    elsif results[q].to_i == 1 then
      win += 1
    else
      puts results[q]
      puts "false"
    end
    q += 1
  end
  i+=1
end
if win == lose then
  puts "true"
else
  puts "false"
end

Answer 1

您可以使用array.each而不是while循环.

您可以使用array.count而不是手动检查每个数组:

lose = results.count { |r| r.to_i == 0 }
win = results.count { |r| r.to_i == 1 }

# or possibly if the array can only contain wins and losses
win = results.count - lose
