Set operators in python

2. Creating a set
Adding elements to set
Removing elements
Union |
Intersection &
Difference –
Symmetric difference ^
Set comprenshive

3. Creating a set
• You can create a set using curly braces {} or the set() constructor.
• Sets are used to store multiple items in a single variable.
• It is a collection which is unordered, unchangeable*, and unindexed

4. Adding the elements
You can add elements to a set using the add()
method:

5. Removing the elements
You can remove elements from a set using the remove() or discard()
method:

6. Union (|)
You can perform a union operation to combine two sets into one, without
duplicates, using the union() method or the | operator:

7. Intersection (&)
You can find the common elements between two sets using the
intersection() method or the & operator:

8. Difference(-)
The difference between two sets A and B include elements of set A that are not present
on set B using the difference() method or the – operator.

9. Symmetric Difference(-)
Set Symmetric Difference The symmetric difference between two
sets A and B includes all elements of A and B without the common
elements using the symmetric_difference() method or the ^
operator:

10. Set comprenshive
Set comprehensions are pretty similar to list comprehensions. The only difference
between them is that set comprehensions use curly brackets { }

11.  The Dutch National Flag problem, also known
as the Three-Way Partitioning problem, is a
famous computer science problem related to
sorting an array of elements containing three
distinct values (usually represented as 0, 1, and
2) in a specific order.
 Here's a Python program that solves the Dutch
National Flag problem using the "Dutch
National Flag Algorithm":

12. Expected Output:
[0,0,1,1,2]

13. The Count and Say problem is a
sequence generation problem. Given
an integer n, the task is to generate the
nth term of the "Count and Say"
sequence.
The sequence starts with "1", and each
subsequent term is obtained by reading
the previous term aloud and counting
the number of digits of the same type in
a row.
