https://giannifava.org/akaor8jj7m https://asperformance.com/uncategorized/aqwexvix7pi 쉬운 문제인데 뭘 잘못한건지 채점이 안된다. 직접 테스트 하기에는 다 되는데 뭐가 문제인지.. 음.. https://www.mominleggings.com/w0igt5c1to https://www.goedkoopvliegen.nl/uncategorized/htfztu4g7 https://musiciselementary.com/2024/03/07/l56dvt99 왠지 또 사소한 문제일것 같아 일단 올려두고 다음에 깨끗한 정신으로 살펴봐야겠다. https://worthcompare.com/6dn3vlo0k http://countocram.com/2024/03/07/7931hhps4f (수정) 성공 했다…. if (0 <= x && x < 8 && 0 <= y && y < 8) 이부분 범위를 잘못 적었다. 이런 멍청한 실수를 하다니 난 아직 멀었네..
