Set in C++ | All You Need to Know About Set in C++
Sets are the containers in C++ STL for storing elements in a given order. The elements of a set must be unique. The value itself can identify each element in a set, i.e., they act as keys themselves. We can insert elements in or remove elements from a set in C++ but cannot modify them since the values become constant once stored in the set.

algorithm – Set Implementation in C++? – Stack Overflow
That is how an std::set<std::vector> can work out of the box. When a new element is inserted, the set does not have to check all the elements. Insertion is a logarithmic complexity operation, which is why the implementation tends to be a self-balancing binary tree (I phrase it with this rather odd causality because the C++ standard does not specify what the implementation should be like, just how it should behave.)

C++ set | How set function work in C++ with Examples – EDUCBA
A set function is part of the standard library of C++, which is used for storing some unique elements and is then used for performing many operations on top of it. This is a function that allows programmers to use the C++ set easily whenever there is a requirement based on key and value pairs.

Sets are a type of associative container in which each element has to be unique because the value of the element identifies it. The values are stored in a specific sorted order i.e. either ascending or descending. Syntax: set setname; Datatype: Set can take any data type depending on the values, e.g. int, char, float, etc. Example:

A Set is a collection of distinct elements. Elements cannot be modified once added. There are various operations associated with sets such as union, intersection, power set, Cartesian Product, set difference, complement, and equality. Methods of Set: add (data) – Adds ‘data’ to the set unionSet (s) – Returns union of set with set ‘s’

C – How to implement Set data structure? – Stack Overflow
There are multiple ways of implementing set (and map) functionality, for example: tree-based approach (ordered traversal) hash-based approach (unordered traversal) Since you mentioned value-indexed arrays, let’s try the hash-based approach which builds naturally on top of the value-indexed array technique.

python – How is set() implemented? – Stack Overflow
To emphasize a little more the difference between set’s and dict’s, here is an excerpt from the setobject.c comment sections, which clarify’s the main difference of set’s against dicts. Use cases for sets differ considerably from dictionaries where looked-up keys are more likely to be present. In contrast, sets are primarily about membership testing where the presence of an element is not known in advance. Accordingly, the set implementation needs to optimize for both the found and not-found …

C++ Program to Implement Set in STL – tutorialspoint.com
Set is abstract data type in which each element has to be unique, because the value of the element identifies it. The value of the element cannot be modified once it is added to the set, but it is possible to remove and add the modified value of that element. Functions and descriptions: Functions used here: st.size() = Returns the size of set. st.insert() = It is used to insert elements to the set. st.erase() = To delete the element from the set. st.find() = Returns an iterator to …

set – C++ Reference – cplusplus.com
Sets are typically implemented as binary search trees. Container properties Associative Elements in associative containers are referenced by their key and not by their absolute position in the container. Ordered The elements in the container follow a strict order at all times. All inserted elements are given a position in this order. Set
