 ## Step 1
-Write some code to construct a whole staircase, out of **bricks**. You will need to change the **second** and **third** coordinate of the **second** parameter in all of the three `||blocks: place block at position||` commands. You will also need to update the data values in the `||blocks: block with data||` commands. Remember, each data value equals direction with stairs.
