Explanation:
Two Factor Authentication, abbreviated as 2FA.
It is a type of authentication that requires the presentation of two credentials for access to personal data and information.
The credentials needed for a 2FA are
1. Either of the following; PIN, Password or Pattern
2. Your device or gadget which could be an ATM Card, Mobile Phone
3. Biometrics such as fingerprint, voice input
Number one is often referred to as "Something you know"
Number two is referred to as "Something you have"
Number three is referred to as "Something you are"
The 2FA doesn't require the three aforementioned credentials. It only needs just two of the credentials to provide its authentication.

// this function will return 1 if the string sent in arguments is palindrome //else it will return 0
int palindrome(int start_of_string, int end_of_string, string &strr)
{
// base case to check if the string is not empty
if (start_of_string>= end_of_string)
return 1;
if (strr[start_of_string] != strr[end_of_string])
return 0;
// recursive call
return palindrome(++start_of_string, --end_of_string, strr);
}
