K. 474. Ann and Bob are playing a word guessing game. Anna thinks of a meaningful Hungarian word of four letters, which Bob is trying to guess. If Bob tries a certain Hungarian word of four letters, Ann will tell him how many of its letters occur in her word, too, and how many of those are in the correct place and how many are in the wrong place. What may have been the word that Ann had in mind? (No knowledge of the Hungarian language is required. Note that O and Ó are different letters in the Hungarian alphabet.)
