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>

int main(){
	int N;
  	char S[50];
  	int count=0;
  	int i;
  	scanf("%d",&N);
  	scanf(" %c",&S[0]);
  	for(i=1;i<N;i++){
      scanf("%c",&S[i]);
  	}
  	for(i=0;i<=N-3;i++){
    	if(S[i]=='A'&&S[i+1]=='B'&&S[i+2]=='C'){
        	count++;
        }
    }
  	printf("%d\n",count);
  	return 0;
}
```
