A small free application which can solve simple Sudokus.
0.Build the process on your own.
1.Put a plain text file named "sudoku.txt" which contains an unsolved sudoku in the same folder with the jar file.
2.Create a batch file to launch the application. (Just like what we do to start Sponge or Spigot Minecraft server.)
The requirement of the format of "sudoku.txt" is as follows:
/.\Make sure there are 9 numbers in one line. '0' represents an unsolved number.
For example: (this one is what I used for debug) ┏━┯━┯━┳━┯━┯━┳━┯━┯━┓ ┃0│0│1┃9│0│0┃0│0│0┃ ┠─┼─┼─╂─┼─┼─╂─┼─┼─┨ ┃0│2│0┃5│0│3┃0│9│0┃ ┠─┼─┼─╂─┼─┼─╂─┼─┼─┨ ┃0│9│5┃0│0│0┃2│6│0┃ ┣━┿━┿━╋━┿━┿━╋━┿━┿━┫ ┃4│0│8┃0│1│0┃0│2│0┃ ┠─┼─┼─╂─┼─┼─╂─┼─┼─┨ ┃0│0│2┃0│6│0┃0│0│4┃ ┠─┼─┼─╂─┼─┼─╂─┼─┼─┨ ┃0│7│0┃0│9│0┃0│0│3┃ ┣━┿━┿━╋━┿━┿━╋━┿━┿━┫ ┃2│0│0┃8│0│0┃0│0│0┃ ┠─┼─┼─╂─┼─┼─╂─┼─┼─┨ ┃5│0│0┃0│0│1┃9│0│2┃ ┠─┼─┼─╂─┼─┼─╂─┼─┼─┨ ┃7│0│0┃0│0│9┃3│0│0┃ ┗━┷━┷━┻━┷━┷━┻━┷━┷━┛
