Problem

Yeongil, who is about to graduate, feels lonelier as Christmas approaches.

For Yeongil's sake, Dongwoo does not set up a blind date, but instead helps Yeongil find an ideal match.

Yeongil, a firm believer in MBTI, is attracted to someone who is the exact opposite of himself. That is, someone whose four MBTI letters are all opposite to his own is Yeongil's ideal type.

MBTI describes personality along the following four scales. Each scale consists of two opposing traits.


Trait		Description
Extroversion (E)	Introversion (I)	Preferred world: the world and others / the inner world
Sensation (S)	iNtuition	Mode of perception: practical perception / perception beyond the real
Thinking (T)	Feeling (F)	Basis of judgment: facts and truth / relationships and people
Judging (J)	Perceiving (P)	Lifestyle: planned living / spontaneous living

Each of the four scales has two possibilities, so 16 types are formed in total. A type is written as four letters, one taken from the alphabet letter for each case. The following are the MBTI types.


Group	Sensing/Thinking	Sensing/Feeling	Intuition/Feeling	Intuition/Thinking
Introversion/Judging	ISTJ	ISFJ	INFJ	INTJ
Introversion/Perceiving	ISTP	ISFP	INFP	INTP
Extroversion/Perceiving	ESTP	ESFP	ENFP	ENTP
Extroversion/Judging	ESTJ	ESFJ	ENFJ	ENTJ
