How do you calculate the length of my program for "The 10 shortest solutions"?

First, we count the total number of bytes in all files. In particular, windows-style newlines `\r\n` are counted as 2 bytes. If you are using windows, you should ensure that you're using Unix-style newlines: `\n`.

Second, we also count the total length of all filenames, including the extension. If the shortest file name has length ≤ 64, then it is not counted. This freebie is only applied for at most one file. In particular, if you only submit a single file with name less than 64 bytes, the file name length is not counted.

The sum of these two parts is the length of your submission.
