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 main()
{
    int n;
    scanf("%d", &n);
    int i;
    int a[100005];
    for (i = 0; i < n; i++)
        scanf("%d", &a[i]);
    int ans = 0;
    for (i = 0; i < n; i++)
        if (i == a[a[i] - 1] - 1)
            ans++;
    ans /= 2;
    printf("%d\n", ans);
    return 0;
}```
