Given a completed Crossword puzzle, extract the words in it with their respective clue numbers, with "across" (horizontal) and "down" (vertical) words grouped and ordered like a real crossword puzzle.
The words are numbered in the row-major order of their first l...

If all uppercase characters are removed from the program, it lowercases all uppercase letters.
If all lowercase characters are removed from the program, it uppercases all lowercase letters.
Transforming characters beyond the basic Lat...
