Oguz Atay Puzzle Contest (OAPC)

Draw a loop into the diagram following the gridlines, which does not touch or cross itself. A digit in a cell indicates the amount of its edges used by the loop.
The loop should pass through all the circles (both black and white). The circles in the diagram follow the following-rules:

1. The path must turn at every black circle.

2. The path cannot turn at any white circle, but must turn immediately before and/or after.
