Description

On an $n × m$ map, there are some mines represented by $1$, while other areas without mines are represented by $0$. If a mine is detonated, its blast range will destroy the land in the surrounding eight positions and the land where the mine is located. If there are mines in its eight surrounding positions, these mines will trigger a chain reaction and continue to detonate. The land after the explosion is represented by $2$. Please write a program to output the appearance of the map after detonating a specific mine.

Input Format

The input consists of $n + 2$ lines:
The first line contains two integers: $n$ ($1≤n≤100$), $m$ ($1≤m≤100$), indicating the size of the map is $n×m$.
Lines $2$ to $n+1$ each contain $m$ characters, representing the appearance of the map.
Line $n+2$ contains two integers: $x$ ($1≤x≤n$), $y$ ($1≤y≤m$), indicating the coordinates of the specified starting (detonation) point on the map. If the specified coordinates are land, there is no need to detonate any mines.

Output Format

Output $n$ lines, each containing $m$ numbers, representing the appearance of the map after the explosion.
