Simple sudoku solver using backtracking. Reading sudoku data from a csv file.

This is just a port from the Java version I created some years ago.

Each csv file represents one sudoku. The sudoku needs to be given in the following format:

• Nine rows in total.

• Each row has to be structured by the following rules:

  • If a number is given, type in that number.
  • If the cell is empty, don't input anything.
  • Separate values by a comma ,.

• Example row: 1,2,3,,5,6,,,9

The solver is now able to compute all possible solutions for a given sudoku.
