如何连接字符串与条件ruby中的每个循环

I'm trying to concatenate 2 consecutive strings if any string length is less than 4 characters, but I'm not successful.

我试图连接2个连续的字符串,如果任何字符串长度少于4个字符,但我没有成功。

The code I have so far is:

我到目前为止的代码是:

strings = ['abnhs', 'iuu', 'poioyw', 'tyr', 'mmkaud']
strings.each do |w|
  if w.length < 4
    temp = w
    next
  end    
  w = temp + w 
  puts w
end

Expected output is:

预期产出是:

abnhs
iuupoioyw
tyrmmkaud

Thanks in advance for any help

在此先感谢您的帮助

You need to declare the temp variable outside of your each block. Try this:

您需要在每个块之外声明临时变量。尝试这个:

strings = ['abnhs', 'iuu', 'poioyw', 'tyr', 'mmkaud']
temp = ''
strings.each do |w|
  if w.length < 4
    temp = w
    next
  end    
  w = temp + w 
  puts w
end
