Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include<stdio.h>

int main() {

	int n;
	int i;
	int flag,count;
	char c[400];
	int Answer[200],a=0;

	for(;;) {
		scanf("%d",&n);
		if(n==0) break;

		for(i=0;i<3*n;i++)
			scanf("%c",&c[i]);

		flag=0,count=0;
		for(i=1;i<3*n;i+=3) {
			if(c[i+1]=='u') {
				if(flag==0) flag++;
				else if(flag==1) {
					count++;
					flag=0;
				}
				else if(flag==-1) flag++;
			}

			else {
				if(flag==0) flag--;
				else if(flag==-1) {
					count++;
					flag=0;
				}
				else if(flag==1) flag--;
			}
		}
		Answer[a]=count;
		a++;
	}

	for(i=0;i<a;i++)
		printf("%d\n",Answer[i]);

	return 0;
}```

Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include<stdio.h>

int main() {

	int n;
	int i;
	int flag,count;
	char c[400];
	int Answer[200],a=0;

	for(;;) {
		scanf("%d",&n);
		if(n==0) break;

		for(i=0;i<3*n;i++)
			scanf("%c",&c[i]);

		flag=0,count=0;
		for(i=1;i<3*n;i+=3) {
			if(c[i+1]=='u') {
				if(flag==0) flag++;
				else if(flag==1) {
					count++;
					flag=0;
				}
				else if(flag==-1) flag++;
			}

			else {
				if(flag==0) flag--;
				else if(flag==-1) {
					count++;
					flag=0;
				}
				else if(flag==1) flag--;
			}
		}
		Answer[a]=count;
		a++;
	}

	for(i=0;i<a;i++)
		printf("%d\n",Answer[i]);

	return 0;
}```
