Command is a behavioral design pattern that encapsulates a request as an object. This allows you to parameterize methods with different requests, delay or queue a request’s execution, and support undoable operations. This pattern promotes the decoupling of the sender and receiver of a request, enhancing flexibility and maintainability.

The State Design Pattern is a behavioral design pattern that allows an object to change its behavior when its internal state changes. This pattern is particularly useful for scenarios where an object can exist in multiple states and its behavior varies based on these states.

Radix sort is a non-comparative sorting algorithm that sorts integers by processing individual digits. Unlike comparison-based algorithms (like Quick Sort or Merge Sort), Radix sort groups numbers by their individual digits.
