Draw a loop along the dotted lines such that each point of the grid is visited at most one time and it is possible to place three zeros in each row and column of the grid. These zeros are valid clues. They must not touch each other, not even diagonally. Clues indicate at how many corners of the cell the loop bends.
Solution code: The size of all areas outside the loop, clockwise beginning top left
