Queues can also be implemented as a purely functional data structure. [3] There are two implementations. The first one only achieves () per operation on average. That is, the amortized time is (), but individual operations can take () where n is the number of elements in the queue.
C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
The programming language C# version 3.0 was released on 19 November 2007 as part of .NET Framework 3.5. It includes new features inspired by functional programming languages such as Haskell and ML, and is driven largely by the introduction of the Language Integrated Query (LINQ) pattern to the Common Language Runtime.

When processes have different priorities the queue may be ordered thereby, such that the highest priority process is taken from the queue first. If the implementation does not ensure atomicity of the increment, decrement, and comparison operations, there is a risk of increments or decrements being forgotten, or of the semaphore value becoming ...
Double-ended queues can also be implemented as a purely functional data structure. [3]: 115 Two versions of the implementation exist. The first one, called 'real-time deque, is presented below. It allows the queue to be persistent with operations in O(1) worst-case time, but requires lazy lists with memoization. The second one, with no lazy ...
The GLib event loop was originally created for use in GTK but is now used in non-GUI applications as well, such as D-Bus. The resource polled is the collection of file descriptors the application is interested in; the polling block will be interrupted if a signal arrives or a timeout expires (e.g. if the application has specified a timeout or ...
A Hoare style monitor with two condition variables a and b. After Buhr et al. We assume there are two queues of threads associated with each monitor object e is the entrance queue; s is a queue of threads that have signaled. In addition we assume that for each condition variable c, there is a queue
[2] [3] [4] It was created in 2008 by Jeff Atwood and Joel Spolsky. [5] [6] It features questions and answers on certain computer programming topics. [7] [8] [9] It was created to be a more open alternative to earlier question and answer websites such as Experts-Exchange.
