Problem 5: Disjoint sets. Consider a list of cities c1, c2, . . . , cn. Assume we have a relationR such that, for any i, j, R(ci, cj ) is 1 if cities ci and cj are in the same province, and 0otherwise.(i) Using a disjoint set data structure, write an algorithm that puts each city in a setsuch that ci and cj are in the same set if and only if they are in the same province.Justify corectness of your algorithm.(ii) If a disjoint set data structure is implemented by trees and in union the name of thenew set is always the name of the larger set, what is the worst-case running time ofyour algorithm.

Assume a generic recursive relation is defined as :A[i] = p*A[i-1] + qwhere p and q are coefficients of the relation. Write a function that takes the first three numbers in this relation as a list,such as [A[0], A[1], A[2]]and computes p and q, and returns A[3]. For example, given [1,3,5] your function should return 7, because the numbers 1,3,5 are produced by the series:A[i] = A[i-1] + 2where p is 1 and q is 2, and then the next number in the series becomes 7. You can assume that p and q are always integers. You can also assume that p and q are determinable in any test case.""" def recursionSolver(values):return # Remove this line to answer this question.

def transitiveclosure(g): """computes the transitive closure of a graph/relation encoded as as a set of 2-tuples""" transitiveclosure: This function should accept sets/frozensets of 2-tuples that encode relations, or equivalently, graphs, and should return the least relation that includes the input relation and is transitive: its transitive closure. E.g., an input frozenset({(1,2),(2,3)}) could correctly result in the value frozenset({(1,2),(2,3),(1,3)}).
Data Structures and Algorithm(C Programmming) You are given a weighted undirected graph G = (V,E), where E and V denote set of edges and vertices, and a minimum spanning tree T of that graph G. Answer the following questions about G and T on minimum spanning trees. (a) Suppose we decrease the weight of one of the edges in G that is not among the edges in T. Suggest an algorithm in plain English that determines whether T is still a minimum spanning tree, and if it is not, calculates a minimum spanning tree of G. Explain the running time of your algorithm. (Note: Your algorithm should be faster than Prim’s and Kruskal’s) (b) Consider the following algorithm running on G = (V,E). Would it calculate a valid MST of G? If yes, explain your reasoning in plain English, if no, provide a counter example graph that the algorithm will fail producing an MST. Also, what is the running time of the algorithm in the previous question. Show your analysis.
