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>
char s[100000];
int main(){
  scanf("%s",s);
  int len=strlen(s);
  int c=0;
  char t=s[0];
  for(int i=0;i<len;i++){
    if(s[i]!=t){
      c++;
      t=s[i];
    }
  }
  printf("%d\n",c);
  return 0;
}
```
