• You can consistently choose any two characters for representing the board.

• You can consistently choose the direction of growth. That is, instead of the above representations (which grow downward and rightward), you can produce any of its reflected or rotated versions.

• Trailing or leading space is allowed, as long as space is not one of the two characters used for the board.

• You can optionally use "\$0\$-indexed" input; that is, take as input \$S-1\$, which specifies a board with \$S\$ layers.

• Output may be through STDOUT or an argument returned by a function. In this case it may be a string with newlines, a 2D character array or an array of strings.

• You can consistently choose any two characters for representing the board.

• You can consistently choose the direction of growth. That is, instead of the above representations (which grow downward and rightward), you can produce any of its reflected or rotated versions.

• Trailing or leading space is allowed (if output is through STDOUT), as long as space is not one of the two characters used for the board.

• You can optionally use "\$0\$-indexed" input; that is, take as input \$S-1\$, which specifies a board with \$S\$ layers.

Output: an ASCII representation of a board with \$S\$ layers.

Output: an ASCII-art representation of a board with \$S\$ layers.

Input: a positive integer \$S\$ representing the number of layers in the board. If you prefer, you may also get \$S-1\$ instead of \$S\$ as input (0-indexed); see below.

• Trailing or leading space is allowed, as long as space is not one of the two characters used for the board.

• You can optionally use "0-indexed" input; that is, take as input \$S-1\$, which specifies a board with \$S\$ layers.

Input: a positive integer \$S\$ representing the number of layers in the board. If you prefer, you may also get \$S-1\$ instead of \$S\$ as input (\$0\$-indexed); see below.
