When we want to insert three nodes which are identified by (3,0), (3,5), (3,1) in order, the processes of searching the insertion points are illustrated by Fig. 5a, b and c, respectively. In Figs. 5a and b, we can locate \(K_{3,4}\) and \(K_{3,5}\) as the needed...
In addition, market statuses may often change from time to time, leading to changes in Big Data since data are “dynamic” in the sense that users may periodically or occasionally insert or delete data in the data storage method, e.g., a database. Such real data may increase/decrease dyn...

std::unordered_setis an associative container that contains a set of unique objects of typeKey. Search, insertion, and removal have average constant-time complexity. Internally, the elements are not sorted in any particular order, but organized into buckets. Which bucket an element is placed into...
