Solirius Sudoku Challenge

Write a script to solve sudoku puzzles.

The script should take a series of puzzles on stdin:

1,809200003400806100001030007640002315000000004507060900020407806104000050030908200
2,000008940089526103670300050103602407064015000000000000090801600200703005005000039

And provide the correct answer on stdout, e.g.

1,879241563453876192261539487648792315392185674517364928925417836184623759736958241
2,532178946489526173671349258153682497764915382928437561397851624246793815815264739

The answers don't need to be provided in the order they are given. The value before the comma is the ID of the puzzle.

You can test your script with this tool using npm:

npx sssc [command to execute your script]

# e.g.
npx sssc node test.js
npx sssc java -jar myapp.jar
