How flames program works?

FLAMES is a playful relationship compatibility game that uses the letters in two names to determine their relationship type. The acronym stands for Friends, Love, Affection, Marriage, Enemy, and Sibling. To play, write down the names, eliminate common letters, count the remaining letters, and use the total to determine the relationship category by counting through the letters of "FLAMES." The outcome is intended for fun and entertainment rather than serious analysis.
