In this chapter, the class to implement the nodes of a linked list is defined as a struct.

In this problem you will implement a function called triangle_countwhich will take as input a graph object G, representing an undirectedgraph G, and will return the number of triangles in G. Do not use anyimports for this problem. To simplify the problem you may assume thateach edge is stored twice in G. That is if an edge goes from u to v then vwill be in u’s collection and u will be in v’s collection. If you would prefer,you may assume that an edge is only stored once. In either case G willneed to be regarded as undirected.

In AList class, we have the get function to return an item at a particular position in list indexed by i. For example, let L=[1,2,3]. A call to L.get (1) will return 2. Write in the answer an enhanced get function to accept negative indices. Specifically, the last item has index -1, the second last item has index -2, and the i-th last item has index -i. For example, let L=[1,2,31. A call to L.get (-1) will return 3. A call to L.get (-2) will return 2. A call to L.get (-3) will return 1. Below is a skeleton of the AList class: template class AList { private: /** The underlying array. */ ItemType *items; /** Stores the current size of the list. */ int count; /** Max number of items allowed. */ int maxCnt; public: // Other functions omitted... ItemType get (int i) { // Copy this function in the answer and write code below this line. } ;

Implementing Set Operations The code template initializes two sets, A and B containing lower case characters as elements.Block 1 computes A-B and prints out the resulting set.In Block 2 write code to compute B-A and output the resulting set.In Block 3 write code to compute A⊕B and output the resulting set. Note that according to the definition of a set, the order of the elements does not matter. In this code, the elements of a set are printed in sorted order so that your output will match the expected output in the test cases. main.py # Initialize sets A and BA = { 'a', 'b', 'c', 'd', 'e', 'f' }B = { 'c', 'd', 'f', 'h', 'j', 'k' } print('A = ', sorted(A))print('B = ',sorted(B))print(' ')#Block 1: computes and prints out the set A - B AminusB = set()for element in A: # this line runs through every element in Aif not(element in B): #A - B is the set of elements that are in A and are not in BAminusB.add(element) # Add it AminusB every element in A if the element is also not in B print('A…
