Chapter 52: Sticks 

You are given a grid containing some black cells. Every non-black cell must contain a horizontal or vertical line segment passing through its center. The finished pattern must satisfy these rules:

• A number written on top of a line gives that line’s total length.
• A line may overlap at most one number clue.
• Numbers in black cells tell you how many line segments connect to that black cell.
