1 Sudoku Solver and Generator
Due: January 22
Implement a Sudoku (see Wikipedia) solver. Your solver should at least work on 3×3 boards (i.e., 81 cells), but ideally it should work on an arbitrary M×N boards.
Also, implement a Sudoku board generator. The generator should
generate a random board—
For the solver and generator, no particular input or output is required.
For the general M×N case, M and N do not have to be unique. An example solved 1x2 board is
1 2 
2 1 
and an example solved 3x2 board is
1 2 3 4 5 6 
4 5 6 1 2 3 

2 3 4 5 6 1 
5 6 1 2 3 4 

3 4 5 6 1 2 
6 1 2 3 4 5
