In ruby you can add methods to existing instances of any class. This allows you to add behavior to and instance of a class without changing the behavior of the rest of the instances of that class. class Example def method1(foo) puts foo end end #defines method2 on object exp exp = E...

Selection sort is a sorting algorithm, specifically an in-place comparison sort. It has O(n2) time complexity, making it inefficient on large lists, and generally performs worse than the similar insertion sort. Selection sort is noted for its simplicity, and it has performance advantages over more c...

I used C# language to implement Selection sort algorithm. public class SelectionSort { private static void SortSelection(int[] input, int n) { for (int i = 0; i < n - 1; i++) { var minId = i; int j; for (j = i + 1; j < n; j++...

Each instantiation and full specialization of the std::atomic template defines an atomic type. If one thread writes to an atomic object while another thread reads from it, the behavior is well-defined (see memory model for details on data races) In addition, accesses to atomic objects may establish...

1. at(pos) Returns a reference to the element at position pos with bounds checking. If pos is not within the range of the container, an exception of type std::out_of_range is thrown. The complexity is constant O(1). #include <array> int main() { std::array<int, 3> arr; ...

There are two options to render components on server: renderToString and renderToStaticMarkup. renderToString This will render React components to HTML on server. This function will also add data-react- properties to HTML elements so React on client won't have to render elements again. import { r...
