n a(n) bin(n) S

- ---- ------ ------------------------------------------------------------

1 1 1 () -> (1)

2 0 10 (1) -> (1,1) -> (0)

3 1 11 (0) -> (0,1) -> (0,1,1)

4 1 100 (0,1,1) -> (0,1,1,1) -> (0,1,0) -> (0,1)

5 1 101 (0,1) -> (0,1,1) -> (0,0) -> (0,0,1)

6 0 110 (0,0,1) -> (0,0,1,1) -> (0,0,1,1,1) -> (0,0,1,0)
