Blacken some cells and draw a closed loop passing every white cell exactly once. The loop leads from the center of a cell to the center of a vertically or horizontally adjacent cell. It is allowed to blacken cells containing numbers, but black cells must not share an edge. There is no connected sequence of white cells in any row or column which extends to more that two regions. Numbers determine the number of black cells in the respective regions.
Solution code: For every row from top to bottom the length of the longest horizontal line.
