tool: D119: Location and Shape Definitions :-



tool: D3: Location gives the co-ordinates of the center element of the shape


tool: D16: The co-ordinates go from (0,0) on BOTTOM LEFT to (n-1,n-1) on TOP RIGHT



tool: D28: Shape gives the orientation of the L shaped tile


tool: D5: Shape 1 means proper L shape


tool: D122: Shape 2 means upside down L shape


tool: D38: Shape 3 means mirrored L shape


tool: D50: Shape 4 means mirrored upside down L shape




tool: D8: Enter the value of 'n' (must be a power of 2) : 

tool: D37: %ld

tool: D82: Enter the co-ordinates of the missing cell :-
