효과가 없는 아니나요

4 입력 xor 문제에 정답이 많아져요.

영화 이미테이션 게임 (2014)에서는 해답을 찾는데 컴퓨터로 0부터 끝 번까지 치루었는데 해를 알았음 굳이 이러는 이유가 없다는 거여요.

반복되는 패턴을 따르는 거이다 이럼 이번에는 -1 0 0 1 이나 -1 1 0 0 으로 틀어요. -1 -1 0 2 이거나 .. -1 -1 -1 3 이거나 .. 사실을 더알고 싶었음 학습 역전파 계산이 아니고 브루트포스를 치면 다알겠쩌.

이럼 0101 1010은 출력이 2가 되버리는거 아니나요. 상한 값이 1이어서 머여도 댔저.
