Suduko solver

[gvp16]

Hi guys, i need to make a suduko solver that completes the grid when you enter some of the numbers.

 

but i cant quite figure out how to do it, one way i can think is to compare all the values from the input boxes in a row/ column, and if they add up to the total then it is correct, but im sure there is a better/ more dynamic way.

 

I dont want someone to do the work for me, just a point in the write direction.

 

Thanks.

Thanks for that, but i just cant get my head round how i check all the rows and colums for the correct combination

You can create a multidemensional array out of the POST elements, so you can easily compare (and thus calculate) a1, b1, c1 or a1, a2, a3 to solve it.

I once wrote one in Standard ML as an extra optional assignment:

And stripped off Danish comments that you probably can't read anyway + stripped sudoku generator (EDIT: well, you probably can't read the source code either, but I posted it anyway in case someone would be interested): http://daniel0.net/sudoku_no_comments.sml
