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 n, m;
int a, b, c;
int i;
int sum, max;

int main(){

  scanf( "%d %d" , &n , &m );

  for( i = 0; i < m; i++ ){
    scanf( "%d %d" , &a , &b );
    c = n - a;
    if( c > 0 ){
      sum += c;
    }
    if( c > max ){
      max = c;
    }
  }

  printf( "%d\n" , sum - max );

  return 0;
}
```
