Then, we compare the topology snapshots bygroups with the set operations, and find that the BGP update based data have bettercompleteness and consistency, while the consistency of the traceroute based data ispoor.
基于集合运算对快照进行了分组比较,发现基于BGP更新消息的数据具有较好完整性和一致性,而基于traceroute的数据一致性较差。

I can write it explicitly. I can write it inside of a FOR loop. And we've started to add, and we'll see a lot more of this, examples of collections of structures so that we don't just have to do something that can be easily described as walking through a set of things but can actually be a collection that you walk through.
我可以明确的写出来,我可以把它在FOR循环的内部写出来，然后我们开始学习了add这个运算符,我们会在以后学习很多的,集合的数据结构的例子,这样一来我们可以进行一些,很简单的遍历集合的操作,我想要为大家指出的最后一件事情是。
