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>
#include<stdlib.h>

int main(){

	int i, j, k, len, flag=0;
	long int count = 0;
	char S[200000];

	scanf("%s", S);

	len = strlen(S);

	i = 0;
	while (i<len-2){
		if (S[i] == 'A'){
			flag++;
			while (1){
				if (S[i + 1] == 'A'){
					flag++;
					i++;
				}
				else if (S[i + 1] == 'B' && S[i + 2] == 'C'){
					count += flag;
					i += 2;
				}
				else{
					i++;
					flag = 0;
					break;
				}
			}

		}else{
			flag = 0;
			i++;
		}
//		printf("%d\n", i);
	}

	printf("%ld\n", count);

  return 0;
}
```
