Dynamic set

A dynamic set is a collection of items that can change over time, with new elements being added and existing ones removed as needed. Think of it like a playlist that can evolve—you can add new songs or remove ones you no longer want. In computing, dynamic sets allow programs to efficiently manage data that varies, enabling flexible and adaptable operations without pre-defining all contents upfront. They are essential in situations where the data cannot be fixed in advance, providing a way to handle changing information smoothly.
