Hi, I'm trying to build a SuDoku 9x9 grid of random numbers with 9 3x3 sub grids, and obviously the numbers 1 - 9 should not repeat in certain parts of the grid. I chose to use a 2d array containing 81 random integers, and then made a function that checked each part of the array to correct numbers that had repeated where they shouldn't.
here is an example of part of the check function:
do
chk[9+1;
5]||
chk[2]||
chk[3]);
I know this must look very crude, but in actual fact it does work, it's just that it seems to get stuck in an infinite loop sometimes when ran. Is this because of using too many 'or' operators.
Don't be too critical, I am pretty new at all this, and there is probably easier an way.
Cheers,
Carl.
p.s. Layman's terms please!
