Problem
Make modifications to the attached Sudoku solution that
1) replace the 2D arrays with vectors
2) add a constructor to the Sudoku class that reads the initial configuration from a file
3) adds a function to the Sudoku class that writes the final Sudoku grid to a file or to the standard output device, cout.
I have this so far but cant get it to work could really use some help.
