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

```c
// AtCoder AGC013 A - Sorted Arrays
// 2020.1.22 bal4u

#include <stdio.h>
#include <ctype.h>
#include <string.h>

#if 1
//int getchar_unlocked(void);
#define gc() getchar_unlocked()
#else
#define gc() getchar()
#endif

int in() {   // 非負整数の入力
	int n = 0, c = gc();
	do n = 10 * n + (c & 0xf); while ((c = gc()) >= '0');
	return n;
}

int main()
{
	int a = 0, f = 0;
	int ans = 1;
	int N = in();
	while (N--) {
		int A = in();
		if (a > 0) {
			if (a < A) {
				if (f < 0) a = 0, f = 0, ans++;
				else f = 1;
			} else if (a > A) {
				if (f > 0) a = 0, f = 0, ans++;
				else f = -1;
			}
		}
		a = A;
	}
	printf("%d\n", ans);
	return 0;
}
```

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

```c
// AtCoder AGC013 A - Sorted Arrays
// 2020.1.22 bal4u

#include <stdio.h>
#include <ctype.h>
#include <string.h>

#if 1
//int getchar_unlocked(void);
#define gc() getchar_unlocked()
#else
#define gc() getchar()
#endif

int in() {   // 非負整数の入力
	int n = 0, c = gc();
	do n = 10 * n + (c & 0xf); while ((c = gc()) >= '0');
	return n;
}

int main()
{
	int a = 0, f = 0;

```

Only output the optimized assembly code. Do not include any other text. Do not write any comments in the assembly code. Wrap the assembly code in ```assembly``` tags.
