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 N;
char S[114514];

int main(void) {
	int i;
	int tangesakura = 0;
	if (scanf("%d", &N) != 1) return 1;
	if (scanf("%114513s", S) != 1) return 1;
	for (i = 0; i < N; i++) {
		if ((S[i] == 'O' && S[i + 1] == 'X') || (S[i] == 'X' && S[i + 1] == 'O')) {
			tangesakura++;
			i++;
		}
	}
	printf("%d\n", tangesakura);
	return 0;
}

```
