수락이는 핸드폰을 하나 가지고 있다
그 핸드폰의 비밀번호는 5자리이다(숫자)
그런데 수락이의 핸드폰이 해킹되서 비밀번호가 바뀌었다
핸드폰 비밀번호 중 확실하게 두번째 자리 수가 3이고 3,4,5번째 자리 수는 짝수이다
그리고 추가적으로 해킹을 한 사람이 첫번째 자리 비밀번호가 수락이가 가장 좋아하는 수라고 했다
수락이가 좋아하는 수의 대한 정보는 주지 않는다
수락이는 핸드폰 비밀번호를 입력하는데 10초가 걸리고 만약 비밀번호가 틀리면 5초 뒤에 새 창이 열린다
10번 비밀번호가 틀리면 1분 뒤에 다시 입력할 수 있다고 할때, 수락이는 최대 몃초 뒤에 핸드폰 비밀번호를 풀 수 있을까?
