Question

目标是让计算机正确猜出玩家的4种颜色序列。玩家通过循环的每个实例猜测一种颜色。如果计算机猜测正确，那么最终输出应该从播放器输出4个正确颜色的序列。允许重复。我正在考虑设置一个数组并将其与第一个元素一起存储。然后推动添加下一个正确的颜色。或者另一种方法是使用| item，index |来执行each.index ？

colors = %w(red green orange yellow blue purple)

guess_counter = 0

while guess_counter < 4 do
  comp_guess = colors.sample 
  puts "Enter your guess: "
  guess = gets.chomp
  puts "Computer guessed: " + comp_guess
  if(guess == comp_guess)
    puts "You got it right."
    puts
  else
    puts "You got it wrong. Guess again."
    puts
  end
end

运行以下程序是一个示例。

Enter your guess:
red
Computer guessed: red
You got it right.

Enter your guess:
blue
Computer guessed: blue
You got it right.

Enter your guess:
yellow
Computer guessed: orange
You got it wrong. Guess again.

Enter your guess:
green
Computer guessed: green
You got it right.

Enter your guess:
orange
Computer guessed: yellow
You got it wrong. Guess again.

Enter your guess:
red
Computer guessed: red
You got it right.

所以输出应该是＆＃34;正确的顺序是红色，蓝色，绿色，红色＆＃34;

似乎你也忘记增加guess_counter（看起来它应该只在猜测正确时增加），如果我们存储正确的猜测，实际上并不需要。否则，每次正确猜测时，只需附加一系列猜测，然后使用join方法打印它：

colors = %w(red green orange yellow blue purple)

correct_guesses = []

while correct_guesses.size < 4 do
  comp_guess = colors.sample 
  puts "Enter your guess: "
  guess = gets.chomp
  puts "Computer guessed: " + comp_guess
  if(guess == comp_guess)
    puts "You got it right."
    puts
    correct_guesses << guess
  else
    puts "You got it wrong. Guess again."
    puts
  end
end

puts "The correct sequence is #{correct_guesses.join(', ')}"

输出结果按颜色顺序排列。用户逐一输入
