WebReachability is designed to bring down the entire top portion of the iPhone’s display so it is within thumb’s reach for one-handed access to apps and content. The feature is invoked by double tapping the Home button on other iPhone models. What is reachability tree? The reachability tree is a rooted tree that consists of N+M nodes. WebJan 1, 2010 · There are numerous applications that need to deal with a large graph, including bioinformatics, social science, link analysis, citation analysis, and collaborative networks. A fundamental query is to query whether a node is reachable from another node in a large graph, which is called a reachability query.
