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>
#include <stdlib.h>

int main()
{
	int i, N, a[200001];
	scanf("%d", &N);
	for (i = 1; i <= N; i++) scanf("%d", &(a[i]));
	
	int ans = N;
	for (i = 1; i <= N; i++) {
		if (a[i] == N - ans + 1) ans--;
	}
	if (ans == N) ans = -1;
	
	printf("%d\n", ans);
	fflush(stdout);
	return 0;
}```
