- Control flow goes like this:
- 
- ```
- # orange path: init
- I # read number
- # green path: main loop
- > # go east (start of loop)
- : # dup input
- 2% # take mod 2 (get lowest bit)
- r< # half-turn right, go east (enter second line)
- \ # swap top two stack items (put bit under input)
- 2/ # divide input by 2 (right shift)
- : # dup input
- n # if input is nonzero, go north (continue loop)
- # else, keep going (enter red path)
- # red path: end
- v> # go south, then east (enter third line)
- } # right rotate stack (put input on bottom)
- K # stack reduce (do until <2 items)...
- O # output number
- @ # end
- ```
