The queue shown below stores integer values. front() is another queue member function that reads the value at the head (front) of the queue and returns it. What value does the head of the queue have at the end of this segment of code?. queue vals;int tmp;vals.push(9);while (vals.front() < 14) { tmp = vals.front(); vals.push(tmp + 3); vals.pop(); vals.push(tmp); } int result = vals.front(); vals.pop();

Give the definition of the removeFront function. This function removes a node from the front of a Deque object, and returns the value that was stored in the removed node. You can assume the calling object is not empty before a removeFront function call.

Double-ended queue (abbreviated to deque) is a generalized version of the queue data structure that allows insert and delete at both ends. We can implement a Deque class using linked lists. In this question, we define nodes for a deque as: struct Node{ int value; Node* next; Node* prev; }; When a Node object is used for linked lists, we use the next pointer to point to its next node in the list, and use the prev pointer to point to its previous node in the list. If one node does not have a next or previous node (which means it is the last or the first node in this list), its corresponding pointer is set to NULL. We can define a Deque class as follows. class Deque{ public: Deque(); // Initialize an empty Deque. void insertFront(int num); // Add a node at the front of Deque. void insertRear(int num); // Add a node at the rear of Deque. int removeFront(); // Delete a node from front of Deque // and return its value. int removeRear(); // Delete a node from rear of Deque // and return its value. int size() const; // Return the number of nodes. /* More member function declarations are omitted */ private: Node* front; Node* rear; }; For each Deque object, we have two pointers, front and rear. The front pointer is used to point to the first node in the list, and the rear pointer is used to point to the last node. If a deque is empty, both pointer are set to NULL.
