Write a Scala program to trim any leading or trailing whitespace from a given string

object Scala_String {
  def main(args: Array[String]): Unit = {
    {
      val str = " Scala Exercises ";

      // Trim the whitespace from the front and back of the String.
      val new_str = str.trim();
      // Display the strings for comparison.
      println("Original String:-" + str);
      println("New String:-" + new_str);
    }
  }
}
