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

```c
// AOJ 408 Cave for Cats		
// 2019.9.29

#include <stdio.h>

#define gc() getchar_unlocked()

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

int stack[1005]; int top;
char f[105];

int main()
{
	int i, c, L;

	L = in();
	for (i = 1; i <= L; i++) {
		c = in();
		if (c > 0) {
			if (f[c]) break;
			f[c] = 1, stack[top++] = c;
		} else {
			c = -c;
			if (f[c] == 0) break;
			if (stack[--top] != c) break;
			f[c] = 0;
		}
	}
	if (i > L) puts("OK");
	else printf("%d\n", i);
	return 0;
}
```
