array based list

An array-based list is a data structure that stores a collection of elements in an array. It provides a way to access elements in the list by their index position, and allows for adding, removing, and modifying elements.

In an array-based list, the elements are stored in contiguous memory locations, which means that elements can be accessed quickly by their index position. The array size is fixed at the time of creation, and the list size cannot exceed this limit. When elements are added or removed, the array may need to be resized, which can be a costly operation.

The advantage of an array-based list is that it provides constant-time access to elements by their index position. However, it may not be efficient for inserting or deleting elements in the middle of the list, as all the elements after the insertion or deletion point need to be shifted to make room or close the gap.

Overall, an array-based list is a simple and efficient data structure for storing a collection of elements, but its performance depends on the specific use case and the operations performed on the list.
