// Scala program of takeRight()  
// method  
  
// Import Queue   
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating a queue  
        val q1 = Queue(5, 2, 13, 7, 1)  
          
        // Print the queue 
        println(q1) 
          
        // Applying takeRight method  
        val result = q1.takeRight(2) 
          
        // Display output 
        print("Queue containing last two elements: " + result) 
          
    }  
}  

Output:

Queue(5, 2, 13, 7, 1)
Queue containing last two elements: Queue(7, 1)

Example #2:

// Scala program of takeRight()  
// method  
  
// Import Queue   
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method

    {  
      
        // Creating a queue  
        val q1 = Queue(5, 2, 13, 7, 1)  
          
        // Print the queue 
        println(q1) 
          
        // Applying takeRight method  
        val result = q1.takeRight(3) 
          
        // Display output 
        print("Queue containing last three elements: " + result) 
          
    }  
}  

Output:

Queue(5, 2, 13, 7, 1)
Queue containing last three elements: Queue(13, 7, 1)
