Kas saaksite selgitada, kuidas on rakendatud Set-tüüpi objekt ja kuidas see programmeerimiskeeles töötab?

An object of type Set is a collection of unique elements, meaning it cannot contain duplicates. In programming languages, Set is usually implemented using hash tables or balanced trees, which provide fast access, addition, and removal of elements.

Working principle:

• When adding an element, Set checks if it already exists in the collection.
• If it does not, it is added.
• When checking for the presence of an element, Set quickly searches for it by key.

For example, in Java:

Set<String> set = new HashSet<>();
set.add("apple");
set.add("banana");
set.add("apple"); // will not be added, as "apple" already exists

System.out.println(set.contains("banana")); // true

Here, HashSet uses hashing to store elements, which ensures operations in amortized time O(1).
