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

```c
#include <stdio.h>
int main(void)
{
    int a,b[2000],i,j,n,m,x,y,z=0;
 
    scanf("%d",&n);
    for (size_t i = 0; i < n; i++)
    {
        scanf("%d",&b[i]);
    }
    for(i=0;i<n;i++)
      for(j=i+1;j<n;j++)
          z+=b[i]*b[j];

          printf("%d\n",z);
        return 0;
}```
