나는 방에 갇혔다.탈출을 위하여 비밀번호를 눌러야 한다.방 안에는 누구도 없다. 힌트는 21칸에21칸인 표 중간에서 개미가 처음으로 벽에 닿을 때까지 걸리는 시간을 입력하면 문이 열린다.(개미는 골뱅이 모양으로 움직이고처음에는 1칸에 1분,2번째는 2칸에 1분,그리고 3번째에는 3칸을 간다.)

 

 

 

 

 

풀이도 올려주세요.

    21*21=441,

    \left( \sum_{n=1}^{29}n \right)+6=\frac{29\times 30}{2}+6=441,

    6/30=0.2min=12sec

    그러므로 29분 12초.
