        val t1 = TreeSet(3, 1, 5, 2, 4)  
            
        // Print the TreeSet 
        println(t1
          
        // Applying toList method  
        val result = t1.toList
            
        // Display output 
        print("Elements in the list: "
            
        for(elem <- result) 
            print(elem + " "
