## Code explanation

If we count the number of characters in `Kraków`, it’ll come out to six. So, why is the correct answer `7`? The reason—history!

Modern computers were first developed in English-speaking countries like the UK and the US. When early developers wanted to encode text in computers that only understood bits, they came up with a method of using a byte (`8 bits`) to represent a character. For example, a is `97` (`01100001`), b is `98`, and so on. One byte is enough for the English alphabet, which has twenty-six lowercase letters, twenty-six uppercase letters, and ten digits. There is even some space left for other special characters (like `9` for “Tab”). This encoding is called **ASCII**.
>Note: To be precise, ASCII uses only `7` bits. Latin-1 extends it to `8` bits.
