💡 Analysis & Explanation

Methodology Check ▼

Implement the rule explicitly: Vowel → +1 position, Consonant → -1 position.

Conversion Set 1 (ACT) ▼

A(+1) is B; C(-1) is B; T(-1) is S. Word becomes 'BBS' (0 Vowels).

Conversion Set 2 (BUS) ▼

B(-1) is A; U(+1) is V; S(-1) is R. Word becomes 'AVR' (1 Vowel).

Conversion Set 3 (CAR) ▼

C(-1) is B; A(+1) is B; R(-1) is Q. Word becomes 'BBQ' (0 Vowels).

Conversion Set 4 (DAD) ▼

D(-1) is C; A(+1) is B; D(-1) is C. Word becomes 'CBC' (0 Vowels).

Compiling the results reveals exactly three configurations (BBS, BBQ, CBC) lacking any vowel representation.
