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 <stdlib.h>
#include <math.h>
#include <limits.h>
#include <string.h>
#define ll long long

int cmpcrois (const void * a, const void * b) {
   return ( *(int*)a - *(int*)b );
}

int cmpdecr (const void * a, const void * b) {
   return ( *(int*)b - *(int*)a );
}


int main()
{
   int N , M;
   scanf("%d %d",&N,&M);

   int X[M];
   int count = 0;

   for (int i = 0;i<M;i++)
   {
       scanf("%d",&X[i]);
   }

   int D[M];

 qsort(X, M, sizeof(int), cmpcrois);

  for (int i = 0;i<M-1;i++)
   {
       D[i]=X[i+1]-X[i];
   }

 qsort(D, M-1, sizeof(int), cmpdecr);

 for (int i = N-1 ;i<M-1;i++)
   {
       count+=D[i];
   }

   printf("%d",count);

    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>
#include <stdlib.h>
#include <math.h>
#include <limits.h>
#include <string.h>
#define ll long long

int cmpcrois (const void * a, const void * b) {
   return ( *(int*)a - *(int*)b );
}

int cmpdecr (const void * a, const void * b) {
   return ( *(int*)b - *(int*)a );
}


int main()
{
   int N , M;
   scanf("%d %d",&N,&M);

   int X[M];
   int count = 0;

   for (int i = 0;i<M;i++)
   {
       scanf("%d",&X[i]);
   }

   int D[M];

 qsort(X, M, sizeof(int), cmpcrois);

  for (int i = 0;i<M-1;i++)
   {
       D[i]=X[i+1]-X[i];
   }

 qsort(D, M-1, sizeof(int), cmpdecr);

 for (int i = N-1 ;i<M-1;i++)
   {
       count+=D[i];
   }

   printf("%d",count);

    return 0;

}
