Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
/*
  AOJ 1027
  Title:

*/
#include <stdio.h>
int K,c;


main()
{
        int i,sum;

        while(EOF!=scanf("%d",&K) && K)
        {
                for(i=0,sum=0;i<K*(K-1)/2;i++)
                {
                        scanf("%d ",&c);
                        sum += c;

                printf("%d\n",sum/(K-1));
