Snow Flake Fractal 2
Problem Statement:
The pre-placed blocks drew the first two segments of the fractal. Add in the necessary blocks to complete the fractal design. Hint: you might want to use a loop to condense the number of blocks needed. Play around to see if you can come up with other alternate designs.
