Write a Scala program to find the first and last element of given list.

Sample Solution:

Scala Code:

object Scala_List
{
  def main(args: Array[String]): Unit = 
 {
   val colors = List("Red", "Blue", " Black ", "Green", " White", "Pink")
   println("Original list:")
   println(colors)  
   println("First element of the said list: " + colors.head) 
   println("Last element of the said list: " + colors.last)    
  }
}

Sample Output:

Original list:
