Suppose you are given an undirected graph G and a start node s. Your task is to design an algorithm that returns FALSE if G is not a tree and returns TRUE and labels each vertex v with the number of nodes in the subtree rooted at v if G is a tree. Note that the orientation of edges is implicit given the start node. Hint: Modify DFS to solve the problem.

Write programs to do BFS and DFS traverse of the graph, based on the adjacent list structure. By using queue, implement the BFS algorithm and print the node sequence. By using recursive method, implement the DFS algorithm and print the node sequence. The source node of the traverse should be input by the user. BFS: DFS:

Kruskal's Algorithm: Kruskal's algorithm is a minimum-spanning-tree algorithm which finds an edge of the least possible weight that connects any two trees in the forest. This algorithm is a Greedy Algorithm. The steps to find a MST using this algorithm are as follows: Sort all the edges in non-decreasing order of their weight. Pick the smallest edge. Check if it forms a cycle with the spanning tree formed so far. If cycle is not formed, include this edge. Else, discard it. Repeat step2 until there are (V-1) edges in the spanning tree. Example with 10 vertices and 20 weighted edges:

Given a singly linked list of integers, reverse the nodes of the linked list 'k' at a time and return its modified list. 'k' is a positive integer and is less than or equal to the length of the linked list. If the number of nodes is not a multiple of 'k,' then left-out nodes, in the end, should be reversed as well.Example :Given this linked list: 1 -> 2 -> 3 -> 4 -> 5 For k = 2, you should return: 2 -> 1 -> 4 -> 3 -> 5 For k = 3, you should return: 3 -> 2 -> 1 -> 5 -> 4 Note :No need to print the list, it has already been taken care. Only return the new head to the list. Input format :The first line contains an Integer 't' which denotes the number of test cases or queries to be run. Then the test cases follow. The first line of each test case or query contains the elements of the singly linked list separated by a single space. The second line of input contains a single integer depicting the value of 'k'. Remember/Consider :While specifying the list…
A directed graph's cycle can be found via Depth First Traversal.If a back edge is found during a DFS, then a cycle exists in a directed graph. In a DFS tree, a back edge is a connection between a node and either itself or one of its ancestors. You must loop through all of the graph's vertices in order to find disconnected DFS trees since for a disconnected graph, we obtain a DFS forest. C++ implementation, write:
Implement the following function, in which a while loop is used to keep taking out two minimum elements from the tree, by calling heapq.heappop (), and then merging them to a new node, and lastly inserting the new node back to tree. Note that: • The new node does not need to have a self.char attribute, so you can let it be None Remember to specify the left and right children nodes correctly for the new node. The function changes tree in place. So, you don't need to return tree In [ ]: def merge_nodes (tree): ### START YOUR CODE ### while(len(tree)>1): # Specify the loop condition (you can use while or for) nodel = None node2 = None merged = None # Create a new node by merging the two popped nodes pass # Remember to specify the left and right children nodes for merged pass # Insert the new node to the tree ### END YOUR CODE ### In [ 1: # Do not change the test code here sample_text = 'No, it is a word.
