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 <string.h>

int main(){
  char s[200005];
  scanf("%s", s);
  int start, end;
  for(int i=0; i<strlen(s); i++)
    if(s[i] == 'A'){
      start = i;
      break;
    }
  for(int i=strlen(s)-1; i>=0; i--)
    if(s[i] == 'Z'){
      end = i;
      break;
    }
  printf("%d\n", end-start+1);
  return 0;
}
```
