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(void){
  int a, z;
  int flag=1;
  int i=0, l;
  char s[200000];
  scanf("%s", s);
  //printf("%s\n", s);
  l=strlen(s);
  while(flag){
    if(s[i]=='A'){
      flag=0;
      a=i;
    }
    i++;
  }
  i=strlen(s);
  flag=1;
  while(flag){
    if(s[i]=='Z'){
      flag=0;
      z=i;
    }
    i--;
  }
  /*
  printf("%d %d\n", a, z);
  for( i=a; i<=z; i++){
    printf("%c", s[i]);
  }
  */
  printf("%d\n", z-a+1);
  return 0;
}```
