25.12.6: Total Network of Friends, Help pls Write a program that prints the total friends between two people.

You should create two sets, one for each person, and add friends (strings) to each set representing the friends of that person.

Then, fill in the totalFriends function that takes the two people as parameters and returns a new set that includes their total friends.

Print out the set of total friends

Hints
There are multiple ways you can do this. Not all of the hints apply to each method.

You can loop over the elements in a set like this:

for (item of your_set. elems()) {
println(item);
}
You can use the set methods union or intersect like this:

// returns the union of a and b
a. union(b);

// returns the intersection of a and b
a. intersect(b);
