👉 A "fluid" in the context of programming and data structures refers to a type of data structure that can efficiently store and manipulate sequences of elements, such as strings or lists, where the order of items matters. Fluids are particularly useful for tasks like string manipulation, where operations such as concatenation, splitting, and searching need to be performed on sequences of characters. They are often implemented using linked lists or other dynamic data structures, allowing for efficient insertion and deletion of elements at any position without the need to shift subsequent elements as would be required with arrays. This makes fluids highly flexible and performant for a wide range of text-based operations.
