Use data structure to hold first position and last position of line // line
- sequence of "0" elements in one of the dimensions in your matrix
Search lines in each dimension and store in array of line[s] //for
optimization, store in separate array for each dimension:
array1stDimension,array2ndDimension, array3Dimension
For each line in array[n]stDimension search intersections( +/- 1 diagonal)
with lines in array[n+1]Dimension (perpendicular),
if found two or more such(perpendicular) lines
search parallel line from array[n]stDimension that
have intersections at least with two of given perpendicular lines
if found, calculate area of such rectangle
and compare to current max value, // here in case of 3d, store rectangle as
surface structure in array
if greater than max value, set max:=
current val and remember coordinates of submatrix
In case of 2d array(matrix), it's all.
For 3d array most easy way is to implement structure surface, and search
intersections with other surface[s] to get cube
