Akkara Loop Logic Challenge | Classic WPC Training Puzzle

Today's Akkara Loop is the first puzzle of this type that I created for the Indian Puzzle Team's practice ahead of the World Puzzle Championship 2009. I have created more of these puzzles, which I will post here later. Akkara Loop Puzzle appeared in "18th World Puzzle Championship, Antalya (Turkey)".

Rules of Akkara Loop Puzzle

Paint some cells black to form a single closed loop that does not touch itself even at a point. Numbers in painted cells indicate the number of unpainted cells in neighbouring squares. Numbers in unpainted cells indicate the number of painted cells in neighbouring squares.
