我很难找到解决这个问题的办法.如何从字符串中删除第一个字,如下面的字符串.
- "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,不知道第一个单词的确切长度,但只是想删除第一个单词.
结果应如下
- "am going to school"
- "is going to school"
- "is going to school"
- "are going to school"
任何帮助？
谢谢
解决方法
- "i am going to school".split(' ')[1..-1].join(' ')
- => "am going to school"
你可以在ruby中的数组中使用两种方法,所以-1是最后一个元素.
