Given two strings first and second, consider occurrences in some text of the form "first second third", where second comes immediately after first, and third comes immediately after second.
Return an array of all the words third for each occurrence of "first second third".
\n
Example 1:
\nInput: text = \"alice is a good girl she is a good student\", first = \"a\", second = \"good\"\nOutput: [\"girl\",\"student\"]\n
Example 2:
\nInput: text = \"we will we will rock you\", first = \"we\", second = \"will\"\nOutput: [\"we\",\"rock\"]\n\n
\n
Constraints:
\n\n1 <= text.length <= 1000text consists of lowercase English letters and spaces.text are separated by a single space.1 <= first.length, second.length <= 10first and second consist of lowercase English letters.text will not have any leading or trailing spaces.给出第一个词 first 和第二个词 second,考虑在某些文本 text 中可能以 \"first second third\" 形式出现的情况,其中 second 紧随 first 出现,third 紧随 second 出现。
对于每种这样的情况,将第三个词 \"third\" 添加到答案中,并返回答案。
\n\n
示例 1:
\n\n\n输入:text = \"alice is a good girl she is a good student\", first = \"a\", second = \"good\"\n输出:[\"girl\",\"student\"]\n\n\n
示例 2:
\n\n\n输入:text = \"we will we will rock you\", first = \"we\", second = \"will\"\n输出:[\"we\",\"rock\"]\n\n\n
\n\n
提示:
\n\n1 <= text.length <= 1000text 由小写英文字母和空格组成text 中的所有单词之间都由 单个空格字符 分隔1 <= first.length, second.length <= 10first 和 second 由小写英文字母组成text 不包含任何前缀或尾随空格。\\u7248\\u672c\\uff1a
