문제

다오와 디지니는 새로운 카트라이더 경주 트랙을 만들고 있다. 경주 트랙은 $H\times W$ 크기의 빈 직사각형 격자판에 $1\times 1$ 크기의 정사각형 타일을 놓는 방식으로 만들어진다. 타일은 길이 그려져 있는 방향에 따라 다음 6가지로 나뉘며, 각각의 타일은 회전해서 놓을 수 있다.

모든 격자칸을 타일로 채우면 경주 트랙이 완성된다. 한 격자판에 여러 개의 경주 트랙을 만들 수도 있기 때문에, 완성된 격자판에서 임의의 두 칸을 잇는 길이 존재하지 않아도 된다. 타일을 배치할 때는 길의 끝이 다른 길의 끝과 이어져 있도록 배치해야 한다. 즉, 길의 끝이 격자판 밖을 향하거나, 이웃한 타일의 길과 이어져 있지 않으면 안 된다.

다오와 디지니는 먼저 타일을 배치할 구역을 나누었다. 다오의 구역에는 다오만 타일을 놓을 수 있고, 디지니의 구역에는 디지니만 타일을 놓을 수 있다. 나머지 칸에는 둘 중 아무나 타일을 놓을 수 있다.

6가지 타일을 사용해서 격자판을 꾸미려는 디지니와 다르게, 다오는 구불구불한 경주 트랙을 좋아해서 ㄱ자 형태로 굽은 길 타일만 사용하기로 했다. 또, 다오는 욕심이 많아서 자기가 놓는 타일의 개수를 최대화하고 싶다. 다오는 자신만의 미적 감각에 따라 타일 몇 개를 먼저 배치했지만, 자기가 놓을 타일의 개수를 최대화하기 위해 나머지 칸을 어떻게 채워야 하는지는 알아낼 수 없었다. 다오가 놓을 수 있는 타일의 최대 개수를 계산해서 다오를 도와주자! (단, 다오가 먼저 배치한 타일도 세어야 한다.)

입력

첫 번째 줄에는 격자판의 세로를 나타내는 $H$와 가로를 나타내는 $W$가 주어진다. $(1 \leq H, W \leq 100)$

두 번째 줄부터 $H$개의 줄만큼 격자판의 정보가 주어진다. 각 줄은 $W$개의 문자로 이루어져 있으며, 각 문자가 나타내는 것은 다음과 같다.

  • 1 : 왼쪽 칸과 위 칸을 잇는 길 타일
  • 2 : 왼쪽 칸과 아래 칸을 잇는 길 타일
  • 3 : 오른쪽 칸과 위 칸을 잇는 길 타일
  • 4 : 오른쪽 칸과 아래 칸을 잇는 길 타일
  • o : 다오만 타일을 놓을 수 있는 칸
  • x : 디지니만 타일을 놓을 수 있는 칸
  • . : 둘 중 아무나 타일을 놓을 수 있는 칸

1234가 나타내는 타일은 다오가 놓은 타일이다.

출력

다오가 먼저 배치한 타일을 포함하여, 다오가 놓을 수 있는 타일의 최대 개수를 출력한다. 만약 조건을 만족하도록 격자판을 채울 수 없거나, 다오가 먼저 배치한 타일이 조건에 어긋나면 -1을 출력한다.

예제 1에 주어진 격자판은 다음과 같다. 파란색 칸은 다오의 구역, 노란색 칸은 디지니의 구역이다.

다음은 다오가 놓는 타일의 개수를 최대화하는 배치의 예시이다. 다오가 배치한 타일은 파란색, 디지니가 배치한 타일은 노란색으로 표시했다.
