Solution: Interlude: Classics
Answer: MYTH CHIEF
Written by Jonah Ostroff
In this interlude, each input produces an output of lorem ipsum text. The text is almost the same as the “standard” lorem ipsum passage:
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
However, some letters are misplaced or missing. With some experimentation, we can determine that there are 9 letters that move around, and in order these are d, u, s, i, m, o, d, u, o. With further experimentation, we can determine how they move around: if the ith letter of the input is the Nth letter of the alphabet, then the ith letter of d, u, s, i, m, o, d, u, o is placed N characters after the previous one. So if the first letter of the input is GB, for example, then the d will be inserted in the 7th position of the text, and the u will be inserted two characters after it. If the input is fewer than 9 letters long, then the remaining characters are not placed. If the input is longer than 9 letters long, then every letter after the 9th is ignored.
With this understanding, we can try to get the moving letters to line up correctly with the original text:
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
The input that creates this (which we find by counting the differences between the positions of the correctly placed characters) is MYTH CHIEF.
