Given words 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
.
For each such occurrence, add "third
" to the answer, and return the answer.
Example 1:
Input: text = "alice is a good girl she is a good student", first = "a", second = "good"
Output: ["girl","student"]
Example 2:
Input: text = "we will we will rock you", first = "we", second = "will"
Output: ["we","rock"]
Note:
1 <= text.length <= 1000
text
consists of space separated words, where each word consists of lowercase English letters.1 <= first.length, second.length <= 10
first
andsecond
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。
- 简单题。给出一个 text,要求找出紧接在 first 和 second 后面的那个字符串,有多个就输出多个。解法很简单,先分解出 words 每个字符串,然后依次遍历进行字符串匹配。匹配到 first 和 second 以后,输出之后的那个字符串。
