Answer 1

0: (MYSTERIOUS ((((7 8) (0 H 0))) (((11 12))) (((A B) (C D))) ((D E F))))
  1: (MAGIC (((7 8) (0 H 0))))
    2: (MAGIC ((7 8) (0 H 0)))
      3: (MAGIC (7 8))
      3: MAGIC returned ((7 8))
      3: (MAGIC (0 H 0))
      3: MAGIC returned ((0 H 0))
    2: MAGIC returned ((7 8) (0 H 0))
  1: MAGIC returned ((7 8) (0 H 0))
  1: (MAGIC (((11 12))))
    2: (MAGIC ((11 12)))
      3: (MAGIC (11 12))
      3: MAGIC returned ((11 12))
    2: MAGIC returned ((11 12))
  1: MAGIC returned ((11 12))
  1: (MAGIC (((A B) (C D))))
    2: (MAGIC ((A B) (C D)))
      3: (MAGIC (A B))
      3: MAGIC returned ((A B))
      3: (MAGIC (C D))
      3: MAGIC returned ((C D))
    2: MAGIC returned ((A B) (C D))
  1: MAGIC returned ((A B) (C D))
  1: (MAGIC ((D E F)))
    2: (MAGIC (D E F))
    2: MAGIC returned ((D E F))
  1: MAGIC returned ((D E F))
0: MYSTERIOUS returned ((7 8) (0 H 0) (11 12) (A B) (C D) (D E F))
