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 d[1000]={0};
  int i=0,j=0,n=0,ans=0;
  scanf("%d",&n);
  ans=n;
  for(i=0;i<n;i++){
    scanf("%d",&d[i]);
  }  
  for(i=0;i<n;i++){
  	for(j=i+1;j<n;j++){
    	if(d[i]==d[j]){
         --ans;
          break;
        }
    }
  }
  printf("%d",ans);
    return 0;
  }
```
