There are only two hard things in Computer Science: cache invalidation and naming things. 计算机科学中只有两件困难的事情:缓存失效和命名规范。 缓存的使用除了带来额外的复杂度以外,还面临如何处理缓存失效的问题。 多线程并发编程需要用各种手段(比如Java中的synchronized volatile)防止并发更新数据,一部分原因就...
TreeItem supports the same event bubbling concept as elsewhere in the scenegraph. This means that it is not necessary to listen for events on all TreeItems (and this is certainly not encouraged!). A better, and far more low cost solution is to instead attach event listeners to the TreeVie...

[LeetCode] 261. Graph Valid Tree You have a graph ofnnodes labeled from0ton - 1. You are given an integer n and a list ofedgeswhereedges[i] = [ai, bi]indicates that there is an undirected edge between nodesaiandbiin the graph....
提到一个Tree,我们会研究一个节点有几个child,尽管graph中没有child这个概念,因为graph是一个只讲究节点间联系,而没有谁在上谁在下的层级(hierachy)结构的. Tree则不同,我们关注root node,即根节点。也关注Tree有几个child节点,即有几个分支。 Tree虽然是一种简单数据结构,但在我们的实际应用中非常有用,所以值...
