Answer 1

从m开始，倒着找就行了

int main()
{
    int n;
    scanf("%d",&n);
    int count = 0;
    while(count < 10 && n>=2)
    {
          int flag = 1;
          for(int i=2;i*i<=n;i++)
          {
                  if(n%2==0)
                  {
                        flag = 0;
                        break;
                  }
          }
          if(flag == 1)
          {
                count++;
                printf("%6d",n);
           }
          n--;
    }
    return 0;
}
