这题精度会让人迷茫的啊。。。。

Posted by ACM06060 at 2007-05-06 11:00:34 on Problem 3231 
	double last_t = time;
	time += min;

	for (i=0; i<sp; i++)
	{
		arr[stack[i]].finish = time;	
		Free += arr[stack[i]].now;
		arr[stack[i]].del = true;
		nLeft--;
	}

	for (i=0; i<nTasks; i++)
	{
		if (!arr[i].del)
			arr[i].left -= arr[i].now*min;
					min改成(time-last_t) 就不行。。。
	}


做的我也迷茫了。。。难道加减法也有误差？？
