연산 ^(자연수)^은 다음과 같다.
^(32)^=101100
^(47)^=1000001
^(27)^=100100
그러면 ^(51)^의 값은 얼마일까?
(제가 계산 실수를 좀 자주 하는 편이라... 혹시라도 오류 있으면 알려주세요!)

절반은 왔습니다. 그 나머지 절반을 채우고, ^(51)^까지 구해야 답입니다.

1의자리가 짝수이면 ^(32)^= 32+3*2*2=44
1의자리가 홀수 이면 ^(47)^=47+(4*7-10)=65 ; (4*7-10의 자리 수*5/2)
^(27)^=27+(2*7-5)=36
^(51)^=51+(5*1-12.5)=43.5 이진수로 101011.1 입니다.

그럴 수도 있겠네요. 단, 저 소수점이 함정... 정답엔 소수점 없습니다.
