Hi, I'm on Christmas Break and am bored out of my mind so i decided that i wanted to write a program that generates a SOLVED Sudoku board, i.e., it has all the numbers filled in. I'm going to write a program later to turn it into an unsolved puzzle. But, I can't think of any way to generate the 9 numbers once in each row and each column. I can get all of them in all of the rows, but not all of the columns , and vise versa.
any help would be greatly appreciated.
