fiquran said:Here is an C++ application. Just to give some hints about the sudoku algorithm. Make sure you change the file extension to .zip, and extract it. The algorithm is like this:
* Find the possible 9 digit number for each row according to the given values (in each row, some numbers should be given, 2-4 numbers out of 9 maybe. If there is no value given for a row, then we have 9! possibilities. If 3 value given, then we have (9-3)! = 6! possible outcome for that specific row.)
* With 9 "for" loops, check the other 2 sudoku conditions (column condition and 3-3 square condition).
The outcome that fulfills all 3 conditions is the answer.
