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(){
	char S[100005];
	int N,i=0,num=0;
	int Y[105];
	scanf("%d",&N);
	scanf("%s",S);
	while(i<N){
		if(S[i]=='X'&&S[i+1]=='O')
			++num,i+=2;
		else if(S[i]=='O'&&S[i+1]=='X')
			++num,i+=2;
		else i++;}
	printf("%d\n",num);

	return 0;
}
```
