Union and Intersection of two sets: A set is a collection of similar elements. A union of two

sets A and B is a set of elements in which each element belongs to set A$,$ set B$,$ or both. It is

represented as A U B$.$

For example:

A $=\{1,3,5,7\}$

B $=\{3,6,7,9,11\}$

then A U B $=\{1,3,5,6,7,9,11\}$

The intersection of two sets A and B is a set of elements in which each element belongs to

both sets A and B$.$ It is represented as A $\backslash$Lambda B$.$

For example $$

A $=\{1,3,5,7\}$

B $=\{3,6,7,9,11\}$

Then A $\backslash$Lambda B $=\{3,7\}.$

Write a function in c$++$ language that takes the following parameters:

Four input parameters : Set A and its size, and the set B and its size.

Four output parameters : Intersect set and its size, Union set and its size

The function should return two arrays and their sizes as output. One array holds the

union of array A and B$,$ and the other holds the intersection of the two sets.

Test you program by writing a main function and passing array A $=\{1,3,5,7\}$ and B $=\{3,$

$6,7,9,11\}.$
