题目大意：

给K个从{1,2，。。。49}中选出的数，从这K个数中选6个升序排列，打印所有情况

解题思路：

模拟题

代码如下：

#include <stdio.h>               

int main()
{
int i,n,i1,i2,i3,i4,i5,i6;
       int a[50];
       scanf ("%d",&n);
       while (n)
       {
         for (i=0; i<n; i++)
          scanf ("%d",&a[i]);

         for (i1=0; i1<n-5; i1++)
           for (i2=i1+1; i2<n-4; i2++)
             for (i3=i2+1; i3<n-3; i3++)
               for (i4=i3+1; i4<n-2; i4++)
                 for (i5=i4+1; i5<n-1; i5++)
                   for (i6=i5+1; i6<n; i6++)
   printf ("%d %d %d %d %d %d\n",a[i1],a[i2],a[i3],a[i4],a[i5],a[i6]);
              scanf ("%d",&n);
              if (n)

            printf ("\n");
       }

return 0;
