문제

유명한 마술사인 이민혁이 사용하는 카드의 뒷 면은 모두 자신이 디자인한 카드이다.

민혁이는 카드 뒷 면 전체를 디자인하지 않고, 왼쪽 위 1/4만 디자인한다. 그 다음 대칭시켜 오른쪽 위를 만들고, 다시 대칭시켜서 아래 부분을 모두 만든다.

이렇게 대칭시켜서 전체를 디자인 한 이후에는, 마술하는데 사용하기 위한 의도된 에러를 넣는다. 에러는 원래 '#'이어야 하는 칸을 '.'로 바꾸거나 '.'이어야 하는 칸을 '#'로 바꾸는 것이다.

왼쪽 위의 디자인과 에러의 위치가 주어졌을 때, 카드 뒷 면 전체 디자인을 구하는 프로그램을 작성하시오.

아래 그림은 민혁이의 카드의 예시이다. (회색 칸은 에러이다)

입력

첫째 줄에 왼쪽 위 부분의 행의 개수 R과 열의 개수 C가 주어진다. (1 ≤ R, C ≤ 50)

다음 R개 줄에는 C개의 문자 '.' 또는 '#'가 주어진다.

마지막 줄에는 에러의 위치 A와 B가 주어진다. (1 ≤ A ≤ 2R, 1 ≤ B ≤ 2C)

출력

카드 뒷 면 전체 디자인을 총 2R개 줄에 걸쳐서 출력한다. 각 줄은 2C개의 문자로 이루어져 있어야 한다.
