In the below input graph, We have two components and thus two disjoint sets. Those are, Now, how we can find the disjoint sets. Here comes the find(X) & UNION (X,Y) ADT operation. The operation finds the set name and here we use array for that. We use a parent...
javadisjoint用法 介绍理解Disruptor是什么的最好方法是将它与目前很好理解和非常相似的东西进行比较。在Disruptor的情况下,这将是Java的BlockingQueue。与队列一样,Disruptor的目的是在同一进程内的线程之间移动数据(例如消息或事件)。但是,Disruptor提供了一些将其与队列区分开来的关键功能。他们是:具有消费者依赖关系图的...

Disjoint sets can be used for a number of math problems but specifically in data structures. In set theory, disjoint sets are two sets which do not share any common observations. In other words, if we take the intersection of two sets and the resulting set is an empty set then the sets...
