How to convert a join mail id with one id
I'm assuming you want to convert a join mail ID (e.g., [email protected][email protected]
) to a single ID (e.g., [email protected]
).
Here's a simple way to do it in most programming languages:
Using a regular expression
You can use a regular expression to extract the usernames and concatenate them with an underscore (_
) in between.
Here's an example in JavaScript:
function convertJoinMailId(joinMailId) {
const regex = /(.+?)\+([^.]+)\./;
const match = joinMailId.match(regex);
if (match) {
const username1 = match[1];
const username2 = match[2];
return `${username1}_${username2}@${joinMailId.split('@')[1]}`;
}
return joinMailId; // return original ID if no match found
}
Using string manipulation
Alternatively, you can use string manipulation functions to achieve the same result:
Here's an example in Python:
def convert_join_mail_id(join_mail_id):
parts = join_mail_id.split('+')
return f"{parts[0]}_{parts[1].split('@')[0]}@{join_mail_id.split('@')[1]}"
Testing the functions
You can test these functions with the following examples:
convertJoinMailId("[email protected][email protected]")
should return"[email protected]"
convertJoinMailId("[email protected]")
should return"[email protected]"
(no change)
Remember to adjust the regular expression or string manipulation code according to your specific requirements and the format of your join mail IDs.
