实习性 动态数组(第二版) 大量数据的管理是很多程序员的心病，很难找到一个速度快、效率高、支持超大规模数据的表动态数组是一个功能强大的列表形数据管理链表，利用它可以轻松实现超大数据量的随机插入、删除、修改等操作，它另外一个特点就是速度极快，内存利用率高。 -Practice of dynamic arrays (Second Edition) a large amount of data management is the heart of many programmers, it is difficult to find a fast, high efficiency, support for ultra-large-scale data table dynamic array is a powerful list of shape data management list using it can easily realize large amount of data random insert, delete, modify, such as operation, it is another feature of this approach is extremely fast, high memory utilization.

计算飞船相对测站的位置矢量单位矢量在赤道坐标系中的三个分量-Calculation of the spacecraft relative position vector of the station unit vector in the equatorial coordinate system of the three subscales

题目描述 假设给我们一个任意的图，它可能是也可能不是DAG（有向无圈图），推广拓扑排序算法，以使得给定有向图G的输入，它的输出是以下两者之一： (a) 一个拓扑排序，于是确定了G为DAG； 或者 (b) G中的一个圈，于是确定了G不是DAG. 注意到输出的解可能不是唯一的，输出任意一个答案即可。 输入 第一行两个数n,m,代表节点数和边数 m行，每行两个数代表一条有向边   测试数据范围：(1
