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 <= 40s consists of uppercase and lowercase English letters and exactly one '@' symbol and '.' symbol.s is a phone number:\n\t10 <= s.length <= 20s consists of digits, spaces, and the symbols '(', ')', '-', and '+'.Compiled with clang 11 using the latest C++ 20 standard.
