Last attempt, as its due in a couple of hours
Here's what i have so far..
> charToGrid :: Char -> Position -> Grid -> Grid
> charToGrid c  (row,col) xs = xs
> charToGrid c (row,col) xs = (changeValue c (concat xs (row*9 + col)))
Using changeValue -
changeValue x 0 (y:ys) = (x:ys)
changeValue x n (y:ys) = y:(changeValue x (n-1) ys)
Would really appritiate any help
