Ruby 从字符串中删除第一个单词

Question

我正在努力寻找解决方案。我如何从下面的字符串中删除字符串中的第一个单词。

     "i am going to school"

     "he is going to school"

     "she is going to school" 

     "they are going to school"

所以字符串可以是任何字符串并且不知道第一个单词的确切长度。但只想删除第一个单词。

结果应该如下所示

      "am going to school"

     "is going to school"

     "is going to school" 

     "are going to school"

有什么帮助吗？

谢谢

Answer 1

"i am going to school".split(' ')[1..-1].join(' ')

=> "am going to school"

您可以在 ruby​​ 的数组中进行双向操作，因此 -1 是最后一个元素。
