Time Complexity for Hashmap Insertion The time complexity for a hashmap does not refer to the time taken to create the hashmap. It refers to the time taken to insert, delete or search for a value based on a given key. Time complexity is normally written using the big-O notation. The ...

In this case, creating a limited query result will reduce the complexity of code needed to create such a screen. In those cases, query results can be limited by applying the limit() keyword to the query. RealmResults<Person> people = realm.where(Person.class) .sort("name") .limit(10)...
