// Creating object
object GfG
{

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

        val q1 = Queue(1, 2, 3, 4, 5)

        // Print the queue
        println(q1)

        // Applying dropRight method
        val result = q1.dropRight(2)

        // Displays output
        print("Queue after dropRight(2) method: " + result)
    }

Output:

Queue(1, 2, 3, 4, 5)
Queue after dropRight(2) method: Queue(1, 2, 3)
