- I'm confused about this question. Any help is appreciated!To finish up the definition of the Node class, we need at least two constructor methods. We definitely want a default constructor that creates an emptyNode, with both the Element and Link members set to null. We also need aparameterized constructor that assigns data to the Element member and setsthe Link member to null.Write the code for the Node class:Can you help me with a C++ programming task I am trying to complete for myself please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix. There are a few tabs: main.cpp, graphType.h, linkedList.h, linkedQueue.h, queueADT.h, minimalSpanTreeType.h, and then two data files labeled: CH20_Ex21Data.txt, CH20Ex4Data.txt
- using the above answer implement a new state which is the "error state" the robot use this state when it has no way to reach for the charging station without completely draining the battery. you should allow the user to enter the starting node number, and the initial battery level.Why do we have to free up a node that we no longer have access to?1-Let’s say you have a variable with a static graph associated with it in the backend that will be executed every time you call .compute on that variable. Is there any way to avoid re-computation of the graph every time you call the .compute method? Consider that you have a significant amount of storage available in this case.
- ADT Graph Iterator: Create either a DFS graph iterator or a BFS graph iterator by implementing java.util.lterator interface. An ADT graph iterator should have a reference to an ADT graph. It should also have a DFS search method or a BFS search method.1. The below method is used to select a nodein map coloring problem.def get_node():mnode = "length = -1for k in cgraph.keys():if(len( cgraph[k]) > length and k not inok Color.keys());length = len(cgraph[k])mnode = kreturn mnode The method will return an empty string when A. All nodes are already assigned colorsB. There is no color remaining for a nodeC. Any two nodes have only one color left Note: Select 1 answer from 3 options.Add a method in the BST class to return the number of thenonleaves as follows:/** Return the number of nonleaf nodes */public int getNumberofNonLeaves()
- Write c++ code Create a BST where each node stores the rollNumber and marks of a student. Your task is toprovide the implementation of following methods.constructorinsertRecord() functionupdateRecord() functioncountOfPassedStudents()showData() functioninside main() function, create an object of BST class.Insert the following data and create the BST according to the marks.● 19L-1941, 71 should be the root node● 19L-1942, 62● 19L-1943, 67● 19L-1944, 54● 19L-1945, 58● 19L-1946, 45● 19L-1947, 29● 19L-1948, 76● 19L-1949, 81● 19L-1950, 92Update the data of following record● Marks of 19L-1944 are 54. Update the marks to 47● Marks of 19L-1949 are 81. Update the marks to 85Call the countOfPassedStudents(). You can either display the count in the same function orreturn the value to main function.Call the showData() function to display all the records of BST in preorder traversal.Note: It is not mandatory to create a template classI could use help, me please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix.
