#include <iostream>
using namespace std;

#define SIZE 10

private:
    int arr[SIZE];
    int front;
    int rear;

public:

        front = -1;
        rear = -1;
    }

    void enqueue(int value) {
        if (rear == SIZE - 1) {
            cout << "Queue is full" << endl;
        } else {
            if (front == -1) {
                front = 0;
            }
            rear++;
            arr[rear] = value;
            cout << "Inserted " << value << " in the queue" << endl;
        }
    }

    void dequeue() {
        if (front == -1) {
            cout << "Queue is empty" << endl;
        } else {

            }
