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(void){
  char S[200];
  scanf("%s",S);
  int leng;
  leng = strlen(S);
  int i,j;
  j=0;
  for(i=0;i<leng/2;i++){
    if(S[i]==S[leng-1-i])
      j++;
  }
  printf("%d",i-j);
  return 0;
}```
