Show that in any group of n people there are two who have an identical number of friends within the group. (Friendship is bi-directional – i.e., if A is a friend of B, then B is a friend of A – and nobody is a friend of themselves.) Solve in particular the following two cases individually:Everyone has at least one friend.

Eight friends A, B, C, D, E, F, G and H are sitting around a circle facing the centre. B is third to the right of A who is third to the right of C. F is second to the right of E who is not an immediate neighbor of B. D sits second to the left of H who sits second to the left of G.. Who sits second to the left of A?Question 21Answera.Eb.Gc.Dd.H

Write a function mutual_friends(list1, list2) that takes two lists of friends (with the guarantee of there being no repeat names in either list), and returns the number of friends in common based on sets. Your function should behave as follows:>>> mutual_friends(["Bob", "Joe"],["Esmerelda"])0>>> mutual_friends(["Bob", "Joe"],["Bob", "Joe"])2>>> mutual_friends(["Bob", "Joe"],["Bob", "Joe", "Keitha"])2
