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>
#define abs(a) ((a)<0 ? -(a) : (a))

int a = 0, b = 0, count = 0;
int ansa, ansb;

void dfs(int num, int n, int flag){
  if(flag == ((1<<n) - 1)){
    ++count;
    if(num == a){
      ansa = count;
    }
    if(num == b){
      ansb = count;
    }
    return;
  }
  for(int i=1; i<=n; i++){
    if(flag & (1<<(i-1)))  continue;
    num = num * 10 + i;
    dfs(num, n, (flag | (1<<(i-1))));
    num = num / 10;
  }
}

int main(){
  int n;  scanf("%d", &n);
  //  printf("%d\n", ((1<<n) -1));return 0;
  int t;
  for(int i=0; i<n; i++){
    scanf("%d", &t);
    a = a * 10 + t;
  }
  for(int i=0; i<n; i++){
    scanf("%d", &t);
    b = b * 10 + t;
  }
  dfs(0, n, 0);
  printf("%d\n", abs(ansb - ansa));
  return 0;
}
```

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>
#define abs(a) ((a)<0 ? -(a) : (a))

int a = 0, b = 0, count = 0;
int ansa, ansb;

void dfs(int num, int n, int flag){
  if(flag == ((1<<n) - 1)){
    ++count;
    if(num == a){
      ansa = count;
    }
    if(num == b){
      ansb = count;
    }
    return;
  }
  for(int i=1; i<=n; i++){
    if(flag & (1<<(i-1)))  continue;
    num = num * 10 + i;
    dfs(num, n, (flag | (1<<(i-1))));
    num = num / 10;
  }
}

int main(){
  int n;  scanf("%d", &n);
  //  printf("%d\n", ((1<<n) -1));return 0;
  int t;
  for(int i=0; i<n; i++){
    scanf("%d", &t);
    a = a * 10 + t;
  }
  for(int i=0; i<n; i++){
    scanf("%d", &t);
    b = b * 10 + t;
  }
  dfs(0, n, 0);
  printf("%d\n", abs(ansb - ansa));
  return 0;
}
```
