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 <math.h>
// using namespace std;
int N;
int i = 2;
int num;
char buf[8], out[20];
char k;
s;
size_t ii;
int main()
{
  s = read(0, buf, 8);
  for (;;)

  {
    k = buf[ii++];
    if (k < '0')
      break;
    N = N * 10 + k - '0';
  }
  // printf("%d\n", N);
  long long ans = (long long)N * (N + 1) - 1;

  for (; i * i <= N; i++)
  {
    num = N / i;
    // ans += (long long)(num - i + 1) * i * (i + num) - i * i;
    ans += (long long)i * ((long long)num * num - i * i + num);
  }
  printf("%lld\n", ans);
}
```

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 <math.h>
// using namespace std;
int N;
int i = 2;
int num;
char buf[8], out[20];
char k;
s;
size_t ii;
int main()
{
  s = read(0, buf, 8);
  for (;;)

  {
    k = buf[ii++];
    if (k < '0')
      break;
    N = N * 10 + k - '0';
  }
  // printf("%d\n", N);
  long long ans = (long long)N * (N + 1) - 1;

  for (; i * i <= N; i++)
  {
    num = N / i;
    // ans += (long long)(num - i + 1) * i * (i + num) - i * i;
    ans += (long long)i * ((long long)num * num - i * i + num);
  }
  printf("%lld\n", ans);
}
```
