Magic Fence

Rules: Fill in marked cells with digits from given range for horizontal rows (at the left of the grid). Digits in any row (of all three directions) cannot repeat and should form consecutive sequence. Then draw a fence –  closed loop going along grid lines, which cannot touch or intersect itself. Digits in a cell shows the number of cell’s edges which belong to the fence.
