(aa 10 2)得到(3 4 5 6 7 8 9 10)

(bb 2 10 4)得到((2 8 9 10) (2 7 9 10) (2 7 8 9) (2 7 8 10) (2 6 9 10) (2 6 8 9) (2 6 8 10) (2 6 7 8) (2 6 7 9) (2 6 7 10) (2 5 9 10) (2 5 8 9) (2 5 8 10) (2 5 7 8) (2 5 7 9) (2 5 7 10) (2 5 6 7) (2 5 6 8) (2 5 6 9) (2 5 6 10) (2 4 9 10) (2 4 8 9) (2 4 8 10) (2 4 7 8) (2 4 7 9) (2 4 7 10) (2 4 6 7) (2 4 6 8) (2 4 6 9) (2 4 6 10) (2 4 5 6) (2 4 5 7) (2 4 5 8) (2 4 5 9) (2 4 5 10) (2 3 9 10) (2 3 8 9) (2 3 8 10) (2 3 7 8) (2 3 7 9) (2 3 7 10) (2 3 6 7) (2 3 6 8) (2 3 6 9) (2 3 6 10) (2 3 5 6) (2 3 5 7) (2 3 5 8) (2 3 5 9) (2 3 5 10) (2 3 4 5) (2 3 4 6) (2 3 4 7) (2 3 4 8) (2 3 4 9) (2 3 4 10) (3 8 9 10) (3 7 9 10) (3 7 8 9) (3 7 8 10) (3 6 9 10) (3 6 8 9) (3 6 8 10) (3 6 7 8) (3 6 7 9) (3 6 7 10) (3 5 9 10) (3 5 8 9) (3 5 8 10) (3 5 7 8) (3 5 7 9) (3 5 7 10) (3 5 6 7) (3 5 6 8) (3 5 6 9) (3 5 6 10) (3 4 9 10) (3 4 8 9) (3 4 8 10) (3 4 7 8) (3 4 7 9) (3 4 7 10) (3 4 6 7) (3 4 6 8) (3 4 6 9) (3 4 6 10) (3 4 5 6) (3 4 5 7) (3 4 5 8) (3 4 5 9) (3 4 5 10) (4 8 9 10) (4 7 9 10) (4 7 8 9) (4 7 8 10) (4 6 9 10) (4 6 8 9) (4 6 8 10) (4 6 7 8) (4 6 7 9) (4 6 7 10) (4 5 9 10) (4 5 8 9) (4 5 8 10) (4 5 7 8) (4 5 7 9) (4 5 7 10) (4 5 6 7) (4 5 6 8) (4 5 6 9) (4 5 6 10) (5 8 9 10) (5 7 9 10) (5 7 8 9) (5 7 8 10) (5 6 9 10) (5 6 8 9) (5 6 8 10) (5 6 7 8) (5 6 7 9) (5 6 7 10) (6 8 9 10) (6 7 9 10) (6 7 8 9) (6 7 8 10) (7 8 9 10))
