Dynamic programming is a technique used to solve complex problems by breaking them down into smaller overlapping subproblems. By storing the results of the subproblems in a cache, we can avoid redundant calculations and improve the overall performance. Here is an example of how dynamic programming can be implemented in C#: “`csharp public class DynamicProgramming …

1. Generics: C# supports generics, which allows you to write flexible and reusable code. Generics allow you to create classes, methods, and interfaces that can work with any data type, rather than the specific types that you define when you write the code. 2. Extension methods: Extension methods allow you to add new methods to …

Here are some performance optimization techniques that can be applied to C# code: 1. Use efficient data structures: Choose the right data structure for the problem at hand. For example, use a HashSet instead of a List for fast membership checks, or use a Dictionary instead of a List when looking up values by key. …

Code refactoring is the process of restructuring existing code without changing its external behavior to improve its readability, maintainability, and performance.
