문제

이 모든 사건의 시작은 2주 전이었다. 그 날 상근이는 복도에 누워서 잠을 자고 있었다. 커다란 돌을 들고 그 옆을 지나가던 민혁이는 복도에서 잠을 자는 사람을 처음봐서 신기하게 쳐다보고 있었다. 그 때였다. 들고 있던 돌을 상근이의 왼 발에 떨어뜨렸다. 상근이는 응급실로 실려갔고, 한 달 동안 침대에 누워서 휴식을 취해야 한다는 진단을 받았다. 민혁이는 미안한 마음에 하던 일을 모두 중단하고 상근이를 간호하기로 했다.

상근이는 2주 동안 온라인 저지 문제를 풀었다. 2주 동안 문제를 풀다보니 게임을 하고 싶어졌고, 마침 민혁이를 이용해서 게임을 하기로 했다.

상근이의 게임은 R×C 보드를 세워놓은 상태에서 진행한다. 맨 처음에 각 정사각형 칸은 비어있거나 벽으로 막혀있다. 상근이는 민혁이에게 돌을 떨어놓을 열을 지시하고, 민혁이는 가장 윗 행의 그 열에 돌을 놓는다. 돌을 놓은 이후에는 중력에 의해서 돌이 떨어지게 된다.

돌에 작용하는 중력은 다음과 같다.

  1. 돌의 아랫칸이 벽으로 막혀있거나 가장 아랫줄이라면, 돌은 그 자리에 그대로 멈춰 있는다.
  2. 돌의 아랫칸이 비어있다면, 돌은 아랫칸으로 이동한다.
  3. 돌의 아랫칸에 돌이 있다면, 돌은 다음과 같이 미끄러진다.
    1. 만약 돌의 왼쪽 칸과 왼쪽-아래 칸이 비어있다면, 돌은 왼쪽으로 미끄러진다.
    2. 만약 돌이 왼쪽으로 미끄러지지 않았고, 오른쪽 칸과 오른쪽-아래 칸이 비어있다면, 돌은 오른쪽으로 미끄러진다.
    3. 위의 두 경우가 아니라면 돌은 그 자리에 멈추고, 다시는 움직이지 않는다.

민혁이는 돌의 이동이 멈춘 이후에 다른 돌을 던지기 시작한다.

보드의 초기 상태와 민혁이가 돌을 놓은 열의 번호가 순서대로 가 주어졌을 때, 모든 돌을 던진 이후에 보드의 상태를 구하는 프로그램을 작성하시오.

민혁이는 항상 제일 윗 칸이 비어있는 칸에만 돌을 던진다. 

입력

첫째 줄에 보드의 크기 R과 C가 주어진다. (1 ≤ R ≤ 30,000, 1 ≤ C ≤ 30)

다음 R개 줄에는 C개의 문자가 주어지며, 보드의 초기 상태이다. '.'는 빈 칸, 'X'는 벽으로 막힌 곳을 나타낸다.

다음 줄에는 돌을 던친 횟수 N이 주어진다. (1 ≤ N ≤ 100,000)

다음 N개 줄에는 돌을 던진 열의 위치가 순서대로 주어진다. (가장 왼쪽 열의 번호는 1번)

출력

총 R개 줄에 걸쳐서 보드의 게임이 모두 끝난 후의 상태를 출력한다. 돌은 'O'로 출력한다.
