Hello rai_gandalf & Admin,
One thing that impressed me is the way khasmoth has written sudoku code. I think its difficult to write a code the especially in c and handle its flow is difficult .... But i found its very difficult to enter each and every values along with its row and col number. i think you have to provide some kind of convincing way to enter all the grid details. But at the end it way good . i can say better than me... I am also working on this sudoku (especially inspired by this forum). Finally, find the solution but its very difficult to handle entire code...So just want to test by you and comment on my code.

To Admin : how do I upload my code to this forum ?...

thanks in advance.
