I've tried using the Concat and ++ functions, but to no avail so far.
Imagine the strings are set out in a 9x9 grid type way, and i have to find
the value of a set position given 2 gird values.
> getCharFromGrid (row,col) g = concat g !!(row * 9) + col
The decleration is
> getCharFromGrid :: Position -> Grid -> Char
Any ideas why its not working?
