SET THEORY USING LIST IN PYTHON

Problem Statement:- In second-year computer engineering class, group A student's play cricket, group B students play badminton and group C students play football. 

Write a Python program using functions to compute the following:-

    a) List of students who play both cricket and badminton

    b) List of students who play either cricket or badminton or both

    c) Number of students who play neither cricket nor badminton

    d) Number of students who play cricket and football but not badminton.

(Note- While realizing the group, duplicate entries should be avoided, Do not use SET built-in functions)
