    def main(args:Array[String]) 
    
      
        // Creating a stack 
        val s1 = Stack(1, 2, 3
          
        // Print the stack 
        println(s1
          
        // Creating an array 
        val arr: Array[Int] = Array(0, 0, 0, 0, 0)  
          
        // Applying copyToArray method 
        s1.copyToArray(arr) 
          
        // Displays output 
        println("Elements in the array: ")
          
        for(elem <- arr)  
            print(elem + " ")
