Gappy

Gappy is a logic puzzle. The aim is to blacken two cells in each row or column, with the distance between the black cells given.

Rules: Colour the neutral cells of the grid black or white. In each row and column, exactly two cells must be black.
Black cells may not be adjacent, not even diagonally. A number at the edge of the grid indicates how many white cells are between the two black cells in each row or column.
