{ "data": { "question": { "questionId": "858", "questionFrontendId": "831", "categoryTitle": "Algorithms", "boundTopicId": 1167, "title": "Masking Personal Information", "titleSlug": "masking-personal-information", "content": "
You are given a personal information string s
, representing either an email address or a phone number. Return the masked personal information using the below rules.
Email address:
\n\nAn email address is:
\n\n'@'
symbol, followed by'.'
somewhere in the middle (not the first or last character).To mask an email:
\n\n"*****"
.Phone number:
\n\nA phone number is formatted as follows:
\n\n{'+', '-', '(', ')', ' '}
separate the above digits in some way.To mask a phone number:
\n\n"***-***-XXXX"
if the country code has 0 digits."+*-***-***-XXXX"
if the country code has 1 digit."+**-***-***-XXXX"
if the country code has 2 digits."+***-***-***-XXXX"
if the country code has 3 digits."XXXX"
is the last 4 digits of the local number.\n
Example 1:
\n\n\nInput: s = "LeetCode@LeetCode.com"\nOutput: "l*****e@leetcode.com"\nExplanation: s is an email address.\nThe name and domain are converted to lowercase, and the middle of the name is replaced by 5 asterisks.\n\n\n
Example 2:
\n\n\nInput: s = "AB@qq.com"\nOutput: "a*****b@qq.com"\nExplanation: s is an email address.\nThe name and domain are converted to lowercase, and the middle of the name is replaced by 5 asterisks.\nNote that even though "ab" is 2 characters, it still must have 5 asterisks in the middle.\n\n\n
Example 3:
\n\n\nInput: s = "1(234)567-890"\nOutput: "***-***-7890"\nExplanation: s is a phone number.\nThere are 10 digits, so the local number is 10 digits and the country code is 0 digits.\nThus, the resulting masked number is "***-***-7890".\n\n\n
\n
Constraints:
\n\ns
is either a valid email or a phone number.s
is an email:\n\t8 <= s.length <= 40
s
consists of uppercase and lowercase English letters and exactly one '@'
symbol and '.'
symbol.s
is a phone number:\n\t10 <= s.length <= 20
s
consists of digits, spaces, and the symbols '('
, ')'
, '-'
, and '+'
.给你一条个人信息字符串 s
,可能表示一个 邮箱地址 ,也可能表示一串 电话号码 。返回按如下规则 隐藏 个人信息后的结果:
电子邮件地址:
\n\n一个电子邮件地址由以下部分组成:
\n\n'@'
字符,后面跟着'.'
字符组成。'.'
不会是域名的第一个或者最后一个字符。要想隐藏电子邮件地址中的个人信息:
\n\n\"*****\"
替换。电话号码:
\n\n一个电话号码应当按下述格式组成:
\n\n{'+', '-', '(', ')', ' '}
这些 分隔字符 按某种形式对上述数字进行分隔要想隐藏电话号码中的个人信息:
\n\n\"***-***-XXXX\"
如果国家代码为 0 位数字\"+*-***-***-XXXX\"
如果国家代码为 1 位数字\"+**-***-***-XXXX\"
如果国家代码为 2 位数字\"+***-***-***-XXXX\"
如果国家代码为 3 位数字\"XXXX\"
是最后 4 位 本地号码示例 1:
\n\n\n输入:s = \"LeetCode@LeetCode.com\"\n输出:\"l*****e@leetcode.com\"\n解释:s 是一个电子邮件地址。\n名字和域名都转换为小写,名字的中间用 5 个 * 替换。\n\n\n
示例 2:
\n\n\n输入:s = \"AB@qq.com\"\n输出:\"a*****b@qq.com\"\n解释:s 是一个电子邮件地址。\n名字和域名都转换为小写,名字的中间用 5 个 * 替换。\n注意,尽管 \"ab\" 只有两个字符,但中间仍然必须有 5 个 * 。\n\n\n
示例 3:
\n\n\n输入:s = \"1(234)567-890\"\n输出:\"***-***-7890\"\n解释:s 是一个电话号码。\n共计 10 位数字,所以本地号码为 10 位数字,国家代码为 0 位数字。\n因此,隐藏后的电话号码应该是 \"***-***-7890\" 。\n\n\n
示例 4:
\n\n\n输入:s = \"86-(10)12345678\"\n输出:\"+**-***-***-5678\"\n解释:s 是一个电话号码。\n共计 12 位数字,所以本地号码为 10 位数字,国家代码为 2 位数字。\n因此,隐藏后的电话号码应该是 \"+**-***-***-7890\" 。\n\n\n
