Examples: 11.E would match 'ooze' and 112.2 would match 'llama'.
Longer example: is entered as ..A122.1R
- Letters one, two and seven are unique unknown letters, so we enter . in those positions.
- Third and ninth letters are known so we enter A and R in those positions.
- Fourth and eighth letters are repeated unknown letters, so we enter 1 in those positions.
- Letters five and six are a different set of repeated unknown letters, so we enter 2 in those positions.
- Thus we enter ..A122.1R and get the only word that matches the pattern: 'chauffeur'.
