Which of the following is NOT a common type of data structure?

The correct choice is based on the distinction between data structures and other programming constructs. Arrays, queues, and stacks are all well-defined types of data structures used for organizing and managing data efficiently.

Arrays provide a way to store elements in a contiguous block of memory, allowing for fast access to elements through indexing. Queues implement a first-in-first-out (FIFO) system, where elements are added to the back and removed from the front, making them ideal for scenarios like task scheduling. Stacks operate on a last-in-first-out (LIFO) principle, where the most recently added element is the first to be removed, commonly used in function calls and backtracking algorithms.

Scripts, however, are not classified as a data structure. They refer to small programs or sequences of instructions that automate tasks, often written in scripting languages. While scripts may use data structures to manage data within the script, the script itself is not a structure but rather a method of executing code.

This understanding highlights why scripts do not fit into the category of common data structures and reinforces the unique roles that arrays, queues, and stacks play in computer science.
