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 <= 1000
text
consists of lowercase English letters and spaces.text
a separated by a single space.1 <= first.length, second.length <= 10
first
and second
consist of lowercase English letters.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。

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
