如何将此循环转换为for循环？

Question

如何将此while循环转换为for循环？

ten_things = "Apples Oranges Crows Telephone Light Sugar"
stuff = ten_things.split(' ')
puts "Wait there are not 10 things in that list. Let's fix that."
more_stuff = ["Day", "Night", "Song", "Frisbee", "Corn", "Banana", "Girl", "Boy"]
while stuff.length != 10
  next_one = more_stuff.pop
  puts "Adding: #{next_one}"
  stuff.push(next_one)
  puts "There are #{stuff.length} items now."
end

我尝试过无限循环

Answer 1

我不明白为什么如果TEncoding.GetEncoding(1251)或for循环是针对它的话，你会为while循环而烦恼。

然而，这将有效：

until

Answer 2

您可以使用

array_name.each { |item|
    break if stuff.length > 10
    stuff.push(item)
}
