测试数据有问题！！！
下面这中输入会超时（应该是无法结束）
int main()
{
    int  x;
    veclen = 0;
    while(scanf("%d", &x) != EOF)
    {
	if(x != 0)
	{
		vec[veclen++] = x;
		while(scanf("%d", &x) ,x) vec[veclen++] = x;
	}
         while(scanf("%d", &sum), sum) { ...}
         veclen = 0;
    }    
    return 0;
}
改成下面这种输入就可以了：(感觉很搞笑)
    veclen = 0;
    while(scanf("%d", &vec[veclen]) != EOF)
    {
        if(vec[veclen] == 0)
        {
	        while(scanf("%d", &sum), sum)
	        {  ...
	           veclen = 0;
		}
	else { veclen ++;}
    }
