 # Introduction
 
 Your best friend has started collecting jigsaw puzzles and wants to build a detailed catalog of their collection — recording information such as the total number of pieces, the number of rows and columns, the number of border and inside pieces, aspect ratio, and puzzle format.
-After solving one of the puzzles to figure out these details, you're now helping fill in the gaps for others in the collection, even when some data is missing.
+Even with your powers combined, it takes multiple hours to solve a single jigsaw puzzle with one thousand pieces — and then you still need to count the rows and columns and calculate the remaining numbers manually.
+The even larger puzzles with multiple thousand pieces look quite daunting now.  
+"There has to be a better way!" you exclaim and sit down in front of your computer to solve the problem.
