Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include <stdio.h>
#include <stdlib.h>
#define rep(i,l,r)for(int i=(l);i<(r);i++)
#define max(p,q)((p)>(q)?(p):(q))

char s[40][40];
int main(){
	int h,w;
	scanf("%d%d",&h,&w);
	rep(i,0,h)scanf(" %s",s[i]);
	int ans=0;
	rep(i1,0,h)rep(j1,0,w)if(s[i1][j1]=='B'){
		rep(i2,0,h)rep(j2,0,w)if(s[i2][j2]=='B'){
			ans=max(ans,abs(i1-i2)+abs(j1-j2));
		}
	}
	printf("%d\n",ans);
}
```
