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
1.Assume some Node class with info link fields . Complete this method in class List that returns a reference to the node containing the data item in the argument findThis, Assume that findThis is in the list public class list { protected Node head ; Protected int size ; Public Node find (char find this) { Node curr = head; while(curr != null) { if(curr.info == findThis) return curr; curr = curr.link; } return -1; } }
class IntBTNode { private int data; private IntBTNode left; private IntBTNode right; } Write a new static method of the IntBTNode class to meet the following specification. Make the method as efficient as possible (do not visit nodes unnecessarily). public static int max(BTNode root) // Precondition: root is the root reference of a nonempty binary SEARCH // tree. // Postcondition: The return value is the largest value in the tree.

Given the following definition for a LinkedList: // LinkedList.h class LinkedList { public: LinkedList(); // TODO: Implement me void printEveryOther() const; private: struct Node { int data; Node* next; }; Node * head; }; // LinkedList.cpp #include "LinkedList.h" LinkedList::LinkedList() { head = nullptr; } Implement the function printEveryOther, which prints every other data value (i.e. those at the odd indices assuming 0-based indexing).
