Tapa #45
Colour the grey cells of the grid black or white. Cells with numbers are always white.
The numbers indicate how many of the orthogonal and diagonal neighbouring cells are black. Each number corresponds to a group of orthogonal black cells, separated by one or more white cells. The position and order of the numbers in a cell are irrelevant.
A question mark represents any number greater than zero.
All black cells must form a single orthogonally contiguous area. The black cells must not cover an area of 2x2.
