Do some math to hardcode the drawings. We can consider this as two operations: line across and lines down.


Do the operations in the order: across, down, across, down, across.

Line Across

Print (H + 1) / 2 stars. Let's call this number W because it is the width of the eight.

Line Down

Print a star; print W - 2 spaces; print another star. (next line)

Do the above W - 2 times.

Time Complexity: \mathcal{O}(H^2)
