My code dies a horrible death on this one.  <laughs>  I think I get a  
right answer, but the wait was embarrassing:

$ time ruby numeric_maze.rb 222 9999
222, 224, 112, 56, 58, 29, 31, 33, 35, 37, 39, 78, 156, 312, 624,  
1248, 2496, 2498, 4996, 4998, 9996, 19992, 19994, 9997, 9999

real    96m13.978s
user    49m27.502s
sys     46m22.817s

Guess I need more than my one optimization now.  <laughs>
