Given the following C code and unoptimized 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[100+1]={0};
  scanf("%s",s);
  int cnt=0, len=strlen(s);
  for(int i=0; i<len/2; i++){
    if( s[i] != s[len-1-i] ){ cnt++; }
  }
  printf("%d",cnt);
  return 0;
}```
