In which cases is it preferable to use a 'list' data structure?

The data structure "list" (for example, List<T> in C#) is preferred when you need to store an ordered collection of elements with the ability to dynamically change its size. It is convenient if you need:

• To frequently add or remove elements (especially at the end of the list).
• To have quick access to elements by index.
• To store elements in the order they were added.

Example of using List in C#:

var numbers = new List<int>();
numbers.Add(1);
numbers.Add(2);
int first = numbers[0]; // access by index

If fast insertion/removal in the middle or element uniqueness is important, other structures like LinkedList or HashSet should be considered.
