Quick Sort is a divide-and-conquer algorithm. It works by selecting a 'pivot' element and partitioning the array into two sub-arrays according to whether elements are less than or greater than the pivot. The sub-arrays are then sorted recursively.
Polymorphism is the ability of a function, object, or variable to take on multiple forms. In OOP, it refers to the ability to redefine methods in derived classes.
The Singleton Pattern is a design pattern that restricts the instantiation of a class to a single instance and provides a global point of access to that instance.
