蓝鸭，红鸭，灰鸭

Question

所以，上周我发布了一个挑战来玩鸭子，鸭子，鹅。这导致许多明尼苏达州人评论他们的地区“灰鸭”变异。

规则如下：

使用此颜色列表：

Red
Orange
Yellow
Green
Blue
Indigo
Violet
Gray

编写一个程序来遵循以下规则：

1. 选择这些颜色中的一种，并将其添加到单词“鸭子”中，并将结果打印到新行。
2. 如果颜色不是“灰色”，重复第一步。
3. 如果颜色是“灰色”，就结束你的程序。

必须遵守的规则：

• 程序不应始终打印相同的行数。
• 它可以从“灰鸭”开始，但不应该一直这样做。
• 每一行都应该有一个鸭子，没有空行输出。
• 在颜色和鸭子之间应该至少有一个空格。
• 重要输出前后的空白并不重要。
• 输出的情况并不重要。
• 颜色可以重复。
• 输出不一定每次都包含所有颜色，但必须有可能您的代码将输出每一种颜色。
• 不能包含上述数组之外的颜色。
• 在你的回答中，灰色或灰色都是可以接受的。
• 颜色不应始终保持相同的顺序。
• 以最短的程序为目标。最小字节数获胜。

示例输出：

Green duck
Orange duck
Yellow duck
Indigo duck
Yellow duck 
Gray duck

感谢迈克·希尔第一次提醒我注意这种变化。

我认为值得注意的是，47%的代码只是从1到8之间选择一个随机整数。

而且，出租车是如此冗长，所以在每种颜色之后硬编码duck\n都要短得多，而不是稍后将其连接起来。

以下是未镀金版本：

解释

v->{                              // Void-accepting void lambda function
  for(int x=9;x>0;)               //  Loop until x is zero
    System.out.println(           //   Print...
        "Grey,Red,Orange,         //       colors, "Grey" first

        .split(",")               //       as an array
          [x+=Math.random()*8-x]  //       pick one randomly, use implicit double to int cast with "x+=<double>-x" trick
        +" duck");                //      Oh, and append " duck" to the color.
