Sudoku solver
Can someone please help me with homewrok? I'm really not sure what should I do with that. I need to programm a sudoku solver. The not filled sudoku should be in second one file in txt. format like that:
000000090
190470608
052819407
200048000
009000500
000750009
907364180
506081074
080000000
and I need to put that in array in the main code where every it should be solved and printed completed.
It should be used just stdio.h library.
Sure we can help, but you need to make a start for yourself.
Can you open the file?
Can you read the file?
Can you store the contents of the file in a suitable data structure?
In short, post the code where you got stuck and ask a question about it.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
This might be an obvious question, but do you know how to solve it by hand?
Once you have it in a data structure, can you work out how to solve it? a.k.a this cell can't be a 1,2,3,5,6,7,8,9 so it has to be a 4
