{ 

    // Main method 
    def main(args:Array[String]) 
    {

        val q1 = Queue(5, 2, 13, 7, 1) 
        
        // Print the queue
        println(q1)
        
        // Applying toArray method 
        val result = q1.toArray
        
        // Display output
        print("Elements in the array: ")
        
        for(elem <- result)
            print(elem + " ")
        
    } 
}

        val q1 = Queue(15, 2, 13, 7) 
        
        // Print the queue
        println(q1)
        
        // Applying toArray method 
        val result = q1.toArray
        
        // Display output
        print("Elements in the array: ")
