LM-Qualitraining 2020 (11): Regionales Yajilin
(Published on 22. January 2020, 20:20 by JonaS2010)
Colour some squares, so that a single closed loop can be drawn through all remaining cells. The loop run horizontally and vertically through the centers of the cells. It can't touch or cross itself. No two black cells can share a border. The grid is split up into different regions. A number in a region indicates the amount of cells that need to be coloured in it.
Solution code: For each row from top to bottom, enter the number of the column where the first black cell appears. (Only the last digit for multi-digit numbers, 0 for a column without a black cell).

Can cells with numbers be coloured? May the loop pass through those cells?
@marcmees: Yes, numbered cells have to be either used by the loop or shaded. A shaded number must still be true for that region.
