In Russia we have something like a tradition - we are looking for lucky tickets.
Here's how a ticket regular ticket looks like:
As you can see, ticket has a six digit number. It's considered lucky if a sum of the first three digits equals to the sum of the last three.
Obviously, the one on t...
Generate IBAN checksum digits
code-golf
Write a program or a function that takes a country code and an account number. It's allowed for a program to take them concatenated, as a country code is always 2 characters long. The algorithm for checksum digit generation is thus (source: https://en.wik...
Imagine a representation of a parking lot like this one:
