Pt 1 was just head and tail. For pt 2 I rewrote the
code to instead build the rope (snake) from head to
tail by always moving the head first and traverse
the body of the snake.
Yes, I think of it as a body of a snake - not knots
on a rope. Child hood memories are to damn colorful
:)
For reference, this is my visually debugging code:
def dbg(seen, snake):
print(snake)
for r in range(-4, 1):
print("".join([v(r, c, snake) for c in range(0, 7)]))
print("")
def v(r, c, snake):
if (r,c) == snake[0]:
return "H"
for i, n in enumerate(snake[1:-1], start=1):
if (r,c) == n:
return str(i)
if (r,c) == snake[-1]:
return "T"
if (r,c) == (0,0):
return "s"
return "."
