Available question text
Two players alternately replace '?' in an even-length digit string with 0–9; Alice wins if the final sums of the first and second halves differ, Bob wins if they are equal. Determine the winner under optimal play by analyzing the initial sum difference and the distribution (counts and parity) of '?' between the two halves, which control how much each player can adjust the final sums.
