## Instructions
创建一个正则表达式chewieRegex使用的*字符匹配所有上下"a"中的字符chewieQuote 。你的正则表达式不需要标志，它不应该与任何其他引号相匹配。
## Tests
```yml
tests:
- text: 您正则表达式chewieRegex应该使用*字符匹配零个或多个a字符。
testString: 'assert(/\*/.test(chewieRegex.source), "Your regex chewieRegex should use the * character to match zero or more a characters.");'
- text: 你的正则表达式chewieRegex应匹配16个字符。
testString: 'assert(result[0].length === 16, "Your regex chewieRegex should match 16 characters.");'
- text: 你的正则表达式应该匹配"Aaaaaaaaaaaaaaaa" 。
testString: 'assert(result[0] === "Aaaaaaaaaaaaaaaa", "Your regex should match "Aaaaaaaaaaaaaaaa".");'

testString: 'assert(!"He made a fair move. Screaming about it can\"t help you.".match(chewieRegex), "Your regex should not match any characters in "He made a fair move. Screaming about it can't help you."");'
- text: '你的正则表达式不应该与"Let him have it. It's not wise to upset a Wookiee."中的任何角色相匹配"Let him have it. It's not wise to upset a Wookiee."'
