Specifically, in the loop that calculates the `base` value, the code was adding 2 when the current element was not greater than the `size` parameter (`base += 2`). Based on the failing test case `test_solve_1`, this should have been a subtraction (`base -= 2`) to correctly compute the expected reward value.\n\nI have updated line 53 of `rewards.py` from `base += 2` to `base -= 2`.
