Challenge
- Make a program that takes input of an integer that's $n > 1$ and print out a staircase using a specific character for stair basing (hashes (
#) for demonstration; you can use spaces, but not tabs or other whitespace characters), slashes (/), and underscores (_). - The basis of the staircase is having the hashes as to act like the stair supporters, in other words, bricks. The bottom stair starts with a slash then as we go higher, an underscore at the spot right next and above the
- Shortest program in each language wins!
