Variation of Cross the Streams rules: Shade some empty cells black to create a single group of black cells that are all connected to each other through their edges. No 2×2 cell area within the grid contains all black cells. Numbers to the left/top of the grid represent the groups of consecutive black cells which are in that row/column in order, either from left to right or from top to bottom. For example, a clue of “3 1” means that the row or column has a group of three consecutive black cells followed by a single black cell, separated by at least one white cell. A question mark (?) represents a group of consecutive black cells whose size is unknown; an asterisk (*) represents any number of unknown groups of black cells, including none at all.

However, all of the across clues are presented as one string (starting with the top row and moving down), and all of the down clues are presented as one string (starting with the leftmost column and moving right). You must figure out how the clues are divided amongst the rows and columns.

For automatic solution checking, the shaded cells must be marked in black or a shade of gray. Note that if you are marking off the clues outside the grid, you should use any color but black or a shade of gray.
