Write a Scala program to merge (concatenate) given lists

object Scala_List
{
  def main(args: Array[String]): Unit = 
 {
   val nums1 = List(1,3,5,7,9)
   val nums2 = List(2,4,6,8,10)
   println("Original Lists:")
   println(nums1)
   println(nums2)
   println("Merge the said two lists using the ++ method:")
   val nums_1 = nums1 ++ nums2
   println(nums_1)
   println("Using ::: way:")
   val nums_2 = nums1 ::: nums2
   println(nums_2)
   println("Using concat method:")
   val nums_3 = List.concat(nums1, nums2)
   println(nums_3)
  }
}
