We have to create a function that receives a connection string with password included and you have to mask the password i.e. change password by asterisks.

Preconditions:

• non empty valid url
• password always next to string section password=
• assume password will not contain ampersand sign for sake of simplicity
• to make it more real it has non ASCII characters
• "password=" and "user" will occur only once

empty passwords are not validated but best solutions take empty passwords into account

Example:

input

jdbc:mysql://sdasdasdasd:szdasdasd:dfsdfsdfsdf/sdfsdfsdf?user=root&password=12345

output

jdbc:mysql://sdasdasdasd:szdasdasd:dfsdfsdfsdf/sdfsdfsdf?user=root&password=*****
