## Description
|
|||
|
|
<section id="description">是时候暂停和测试你的新正则表达式写作技巧了。一群罪犯逃出监狱逃跑，但你不知道有多少人。但是，你知道他们和其他人在一起时会保持紧密联系。你有责任立刻找到所有的罪犯。下面是一个查看如何执行此操作的示例：regex <code>/z+/</code>在连续出现一次或多次时匹配字母<code>z</code> 。它会在以下所有字符串中找到匹配项： <blockquote> “Z” <br> “ZZZZZZ” <br> “ABCzzzz” <br> “zzzzABC” <br> “abczzzzzzzzzzzzzzzzzzzzzabc” </blockquote>但它没有在以下字符串中找到匹配项，因为没有字母<code>z</code>字符： <blockquote> “” <br> “ABC” <br> “ABCABC” </blockquote></section>
