I solved your challenge @IceCube

That was a fun one, regardless of its simplicity. The only thing I require for this one is to create a Sudoku solver and parser to submit to my sudoku solver. I only created one in C# a long time ago. I'm attempting this one in C++.

I don't quite understand this though:

Format:
a) "[1-9] [1-9] [1-9]" - coords and input digit
b) "solution [1-9]{81}" - full solution

How does "solution _____" get submitted? (Maybe I should rephrase this)

How is "[1-9]{81}" a full solution for a particular sudoku puzzle? I know solution is the string command, and the argument after it is to be the solution, but I don't get how the solution is to be formatted.

I was looking at Sudoku today, and I can't get what this means: "[1-9]{81}"

"To figure this out, or

*to stay confused*, that's the question"

edit: Hmmm, {81} an index on the 9x9 grid (the very last square? Being a number indicated by the [?]? (ie. a value from 1-9)?

If that's correct, is that how all squares need to be filled in?

Hmm...

**edit: I figured it out for inputting data finally... Shouldn't have taken that long.** At first I thought the coordinates meant grid, then position within the grid, then I tried with the brackets around each 3 numbers, which might have been my biggest mistake. ({X} {Y} {Number})

Still don't understand format b however.
