Write a Scala program to add each element n times to a given list of integers

object Scala_List {    
  def n_times_elements[A](o_list:List[A], n: Int):List[A] = {
    o_list flatMap { element => List.fill(n)(element)  }
    }
  
  def main(args: Array[String]): Unit = {
     val nums = List(1,2,3,3,4,5,6,7)
     println("Original List:")  
     println(nums)
     val result = n_times_elements(nums, 3)
     println("Add each element 3 times to a given list of integers:")
     println(result)     
    }
}
