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.
'?' means, that it is a one-digit number. '??' means that it is a two-digit number, but without beginning with a '0'.
Solution code: The sizes of all areas outside the loop - clockwise and beginning at the top left corner. X for an area with a size of at least 10.
