3×3 하위 행렬로 구성된 비어 있지 않은 이진 행렬은 나란히 놓입니다.

태스크

귀하의 작업은 3×3 하위 매트릭스 중에서 유효한 주사위 패턴 (아래 설명 참조)을 식별하는 것입니다. 각 유효한 패턴은 해당 주사위의 가치가 있습니다. 유효하지 않은 패턴은 0입니다.

산출

유효한 주사위 값의 합입니다.

주사위 패턴

$$\begin{align} &1:\pmatrix{\color{gray}0,\color{gray}0,\color{gray}0\\\color{gray}0,1,\color{gray}0\\\color{gray}0,\color{gray}0,\color{gray}0} &&2:\pmatrix{1,\color{gray}0,\color{gray}0\\\color{gray}0,\color{gray}0,\color{gray}0\\\color{gray}0,\color{gray}0,1}\text{or}\pmatrix{\color{gray}0,\color{gray}0,1\\\color{gray}0,\color{gray}0,\color{gray}0\\1,\color{gray}0,\color{gray}0}\\ &3:\pmatrix{1,\color{gray}0,\color{gray}0\\\color{gray}0,1,\color{gray}0\\\color{gray}0,\color{gray}0,1}\text{or}\pmatrix{\color{gray}0,\color{gray}0,1\\\color{gray}0,1,\color{gray}0\\1,\color{gray}0,\color{gray}0} &&4:\pmatrix{1,\color{gray}0,1\\\color{gray}0,\color{gray}0,\color{gray}0\\1,\color{gray}0,1}\\ &5:\pmatrix{1,\color{gray}0,1\\\color{gray}0,1,\color{gray}0\\1,\color{gray}0,1} &&6:\pmatrix{1,\color{gray}0,1\\1,\color{gray}0,1\\1,\color{gray}0,1}\text{or}\pmatrix{1,1,1\\\color{gray}0,\color{gray}0,\color{gray}0\\1,1,1} \end{align}$$

예

다음 행렬의 예상 출력 은 주사위 5 , 6 및 3 을 포함하고 유효하지 않은 패턴 (왼쪽에서 오른쪽으로, 위에서 아래로)을 포함하므로 14 입니다.

$$\pmatrix{1,0,1,1,1,1\\ 0,1,0,0,0,0\\ 1,0,1,1,1,1\\ 1,0,0,0,0,0\\ 0,1,0,0,1,0\\ 0,0,1,0,1,0}$$

규칙

• 행렬의 너비와 높이는 모두 3의 배수로 보장됩니다.
• 그리드에 올바르게 정렬되지 않은 하위 행렬을 무시해야합니다 (3 차 테스트 사례 참조). 보다 공식적이고 0- 인덱싱 가정 : 고려할 각 하위 행렬의 왼쪽 위 셀의 좌표는 입니다.( 3 x , 3 y)
  $(\mathrm{삼}\mathrm{엑스},\mathrm{삼}\mathrm{와이})$

  $(3x, 3y)$

• 이것은 code-golf 입니다.
