## 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 /z+/在连续出现一次或多次时匹配字母z 。它会在以下所有字符串中找到匹配项： “Z”
“ZZZZZZ”
“ABCzzzz”
“zzzzABC”
“abczzzzzzzzzzzzzzzzzzzzzabc”
但它没有在以下字符串中找到匹配项，因为没有字母z字符： “”
“ABC”
“ABCABC”
## Instructions
写一个greedy正则表达式，在一群其他人中找到一个或多个罪犯。罪犯由大写字母C 。
## Tests
```yml
tests:
- text: 您正则表达式应该匹配one犯罪（“ C中”）， "C"
testString: 'assert("C".match(reCriminals) && "C".match(reCriminals)[0] == "C", "Your regex should match one criminal ("C") in "C"");'
- text: 您正则表达式应该匹配two罪犯（“ CC中”） "CC"
testString: 'assert("CC".match(reCriminals) && "CC".match(reCriminals)[0] == "CC", "Your regex should match two criminals ("CC") in "CC"");'
- text: 你的正则表达式应匹配"P1P5P4CCCP2P6P3"中的three罪犯（“ CCC ”）
testString: 'assert("P1P5P4CCCP2P6P3".match(reCriminals) && "P1P5P4CCCP2P6P3".match(reCriminals)[0] == "CCC", "Your regex should match three criminals ("CCC") in "P1P5P4CCCP2P6P3"");'
- text: 你的正则表达式应匹配"P6P2P7P4P5CCCCCP3P1"中的five罪犯（“ CCCCC ”）
testString: 'assert("P6P2P7P4P5CCCCCP3P1".match(reCriminals) && "P6P2P7P4P5CCCCCP3P1".match(reCriminals)[0] == "CCCCC", "Your regex should match five criminals ("CCCCC") in "P6P2P7P4P5CCCCCP3P1"");'
- text: 你的正则表达式不应该匹配""中的任何罪犯
testString: 'assert(!reCriminals.test(""), "Your regex should not match any criminals in """);'
- text: 你的正则表达式不应该匹配"P1P2P3"中的任何罪犯
testString: 'assert(!reCriminals.test("P1P2P3"), "Your regex should not match any criminals in "P1P2P3"");'
- text: 您正则表达式应该与fifty的罪犯（“ CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC中”） "P2P1P5P4CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCP3" 。
testString: 'assert("P2P1P5P4CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCP3".match(reCriminals) && "P2P1P5P4CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCP3".match(reCriminals)[0] == "CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC", "Your regex should match fifty criminals ("CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC") in "P2P1P5P4CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCP3".");'
```
