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>
#include <string.h>
int main(){
  int n;
  int tmp;
  int ans = 0;

  scanf("%d", &n);

  if(n /1000 == 2){
    ans++;
  }

  tmp = n / 1000;
  if((n - tmp*1000)/ 100 == 2){
    ans++;
  }

  tmp = n / 100;
  if((n - tmp*100) / 10 == 2){
    ans++;
  }

  tmp = n / 10;
  if((n - tmp*10) == 2){
    ans++;
  }

  printf("%d", ans);
  
  printf("\n");


}
```
