# CPR Number

## Question

{% embed url="<https://open.kattis.com/problems/cprnummer>" %}

## Solution

### Idea

This is a give-away question. If I have to say something about this question, it will be very very basic **string manipulation**. Why "very very basic" because all the manipulations need to be hard-coded :joy:

### Code
