[单选题]由元素序列{27，16，75，38，51}构造平衡二叉树，则首次出现的最小不平衡子树的根(即离插入节点最近且平衡因子的绝对值为2的节点)为(9)。

75

解析：解析：二叉排序树的构造方法如下：每读入一个数据，建立一个新节点，若二叉排序树非空，则将新节点的值与根节点的值比较，。如果小于根节点的值，则插入到左子树中，否则插入到右子树中；若二叉排序树为空，则新节点作为二叉排序树的根节点。节点的平衡因子是指节点右子树深度与左子树深度之差。由数据{27，16，75，38，51}构造平衡二叉树，插入51后首次出现不平衡子树，易知最小不平衡子树的节点为75。

[多选题]●Border Gateway Protocol(BGP) is inter-autonomous system (71) protocol. BGP is based on a routing method called path vector routing. Distance vector routing is not a good candidate for inter-autonomous system routing because there are occasions on which the route with the smallest (72) count is not the preferred route. For example, we may not want a packet through an not secure even though it is the shortest route. Also, distance vector routing is unstable due to the fact that the routers announce only the number of hop counts to the destination without actually defining the path that leads to that (73) ．A router that recevives a distance vector advertisement packet may be fooled if the shortest path is actually calculated through the receiving router itself. Link (74) routing is also not a good candidate for inter-autonomous system routing because an Internet is usually too big for this routing method. To use link state routing for the whole internet would require each routex to have a huge link state database. It would also take a long time for each router to calculate its rousting (75) using the Dijkstra algorism.（71）
