Alternative or Complementary methods
Use Mastermind Black/White Peg Feedback: Mastermind distinguishes exact-position matches from remaining matching symbols. Multiset consumption prevents overcounting duplicates. For a complementary task, use Scrabble Letter Tile Values Lookup: Scrabble tile totals depend on caller letter values and blank positions. A blank scores zero regardless of its displayed letter.
