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(void){
	int n,i,cnt=0;
	char s[50];
	scanf("%d%s",&n,s);
	for(i=0;s[i+2]!='\0';i++){
		if(s[i]=='A'){
			cnt+=s[i+1]=='B'&&s[i+2]=='C';
		}
	}
	printf("%d",cnt);
	return 0;
}
```
