    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating stack
        val s1 = Stack(1, 3, 2, 1, 2, 1, 3, 2, 3, 3
          
        // Print the stack
        println(s1
          
        // Applying distinct() method  
        val result = s1.distinct
          
        // Display output 
        print("Stack with distinct elements: " + result)
