Hard input constraints:
- inputs are 3x3
- inputs contain only 2 colors monocolored: black and another
Hard output constraints:
- output is 3x input width and height. Suggests that the output is a 3x3 grid based on the input.
- stronger: if output is split as a 3x3 grid, then each 3x3 block is either black or a copy as input. Which is which?
- stronger: each pixel of the input determines if block is black or copy (final solution)
- output contains only two colors: black and another
Input output comparison:
- input appears pasted on output multiple times: suggests it is being copy pasted
