Cubes

Details

Draw 7 cubes in increasing size using "╱" (U+2571) for the diagonal edges, "│" (U+2502) for the vertical edges, "─" (U+2500) for the horizontal edges, and "█" (U+2588) for the vertices. The cubes should range from size 1 to size 7 with a blank line between each cube. A size 1 cube should look like:

  █────█
 ╱    ╱│
█────█ │
│    │ █
│    │╱
█────█

And a size 7 cube should look like:
