Program Plan Intro

Given Code:

/* Add weighted edges in a new Array List by importing from Priority Queue class*/

List<PriorityQueue<WeightedEdge>> queues = new ArrayList<>();

/* using queue.get() method add new weighted edges with their respective weights*/

queues.get(0).offer(new WeightedEdge(0, 2, 3.5));

queues.get(0).offer(new WeightedEdge(0, 6, 6.5));

queues.get(0).offer(new WeightedEdge(0, 7, 1.5));

queues.get(1).offer(new WeightedEdge(1, 0, 3.5));

queues.get(1).offer(new WeightedEdge(1, 5, 8.5));queues.get(1).offer(new WeightedEdge(1, 8, 19.5));

/* using peek() method of queue compare the weighted edge with index 0 with  index 1*/

System.out.println(queues.get(0).peek().compareTo(queues.get(1).peek()));

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).
