I am trying to write a card shuffler, and I know the method by which I wish to shuffle the cards.However, I am at a loss of the best object-oriented way in which to write it.
I am looking for a memory and performance efficient implementation of SortedSet<T> (corresponding to System.Collections.Generic.SortedSet<T> in vanilla .NET).
I need to store a large number of Long values in a SortedSet implementation in a space-efficient manner.I was considering bit-set implem开发者_如何学运维entations and discovered Javaewah.However, the
I\'m writing a contact book application in Java. The Contacts are displayed on a JList which uses a Sorted TreeSet list model.
What is the fastest way to union 2 sets of sorted values? Speed (big-O) is important here; not clarity - assume this is being done millions of times.
The redis documentation for ZADD states the operation is O(log N). However,开发者_如何学JAVA does anyone know if ZADD is better than O(log N) when the inserted element is at the beginning or end of t
The Jedis call I\'m using returns a Set, although at runtime it is actually a LinkedHashSet. I want to pull it into Scala, deseria开发者_如何学编程lize the elements, and return a Seq.Easy!
I can find an element in a sorted set (backed by BST) in O(logN). Now I would like the index of this element. For example, in set {1, 3, 4, 10}, the index of 4 is 2 and the index of 1 is 0.
I have this segment of Scala code which defines an orderi开发者_JS百科ng and applies it to a TreeSet.This part compiles fine.
The Redis documentation on transactions gives an example of how to implement 开发者_开发百科ZPOP. How do I implement ZMOVE for Redis sorted sets (analagous to SMOVE)?Is this right? .. to move an eleme
