&lt;/div&gt;
&lt;/div&gt;&lt;p&gt;보드판을 string &amp;lsquo;0&amp;rsquo;을 배치시켜 만들었다. 원래 숫자로 넣었는데 False일 떄와 0일때가 같이 취급되어서 따로 만들었다. 아무 선택되지 않은 좌표는 &amp;lsquo;0&amp;rsquo;, 공격당할 수 있기 때문에 놓을 수 없는 곳은 False, 퀸이 위치한 곳은 True로 설정하였다. 우선 임의의 좌표 (p,q)에 퀸을 놓았을 때 퀸이 공격할 수 있는 곳을 False 처리하는 코드를 작성했다. 임의의 좌표의 좌 우 대각선을 바꿔주는 함수를 각각 만들고 하나의 함수로 합쳤다(&lt;code&gt;check&lt;/code&gt;). &lt;code&gt;search&lt;/code&gt;는 특정 행에서 퀸을 놓을 수 있는 열을 찾아 존재하면 boolean값을 반환해주는 함수이다.&lt;/p&gt;</description>

&lt;/div&gt;
&lt;/div&gt;&lt;p&gt;처음엔 DFS로 시도했다. 여러 case가 규칙성 없이 나타날 수 있다고 생각했기 때문이다. 하지만 시간초과가 발생했다. 불필요한 탐색을 줄이기 위해, 값을 최소힙에 저장하도록 했다. DFS 과정 상 재귀 중에 이미 최소힙에 존재하는 최솟값을 넘어선 경우 탐색을 중단하도록 했다. 하지만 시간초과가 계속 발생했다.&lt;/p&gt;</description>
