Each number outside the diagram represents one group of connected fields within the loop in this row/column, in correct order. Each number is equal to the edges of the fields of its group which are used by the loop. Different groups must have at least one field outside the loop between them.
Replace the letters by digits 1-9. Equal letters mean equal digits, different letters mean different digits.
'?' means that there's a single figure (1-9) hidden.
Solution code: The sizes of all areas outside the loop - clockwise and beginning at the top left corner.
