Your second function is called “isTree". Its input is a graph G, which is a dictionary whose keys are the vertices, and whose values are lists of vertices that are adjacent to the given vertex. Its output is True if G is a tree and False if G is not a tree. Hint: You may want to make use of your "connected" function from the last coding assignment.

Q1. Consider the following sequence of numbers: 15, 20, 24, 10, 13, 7, 30, 36, and 25. Insert these numbers one by one into an initially empty red-black tree, and illustrate the tree after each insertion. rotation is needed, present the status before and after the rotation and indicate which rotation is applied. For each node, indicate the color for each node like 15(RED) or 30(BLACK), Ensure that the tree maintains its red-black properties throughout the process. Q2. Given the following sets: A = {2, 4, 6, 8, 10}, B = {1, 3, 5, 7, 9}, C = {1, 2, 3, 4, 5}, and D = {5, 6, 7, 8, 9). Calculate the following set operations and provide the resulting sets: A U B, An C, B n D, (A U B) - C, and (C n D) A (AN B).
