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(){

  int n,i,count;
  char str0[3],str1[3];

  while(scanf("%d",&n),n){
    
    count=0;
    scanf("%s",str0);
    
    
    for(i=1;i<n;i++){
      scanf("%s",str1);
      
      if(str0[1]==str1[1]){
	count++;
      }
      strcpy(str0, str1);
    }
    
    printf("%d\n",count);
    
  }
  
  return 0;
}```
