  Here’s what your mystery function appears to do based on 30 tests:

  - It returns "East" when the first argument a is at least around 21.
  - It returns "North" otherwise.
  - The second argument b (including negatives and zeros) doesn’t affect the output in any case we tried.

  Evidence:
  - East: (21,6), (28,8), (100,1) — all have a ≥ 21.
  - North: all other tested pairs, including many where a < 21, various b values (positive, zero, negative), and swapped orders.

  Note: We didn’t test a = 20 or 19, so the exact cutoff is inferred from the smallest “East” we observed (a = 21). It’s consistent with “East if a ≥ 21; North
  otherwise.”

  From tests, the function returns "East" when a >= 21 and "North" otherwise. Since a = 64 >= 21, it should return "East".

  `East`
