Write a Scala program to create a new string where 'if' is added to the front of a given string. If the string already begins with 'if', return the string unchanged

object scala_basic {
  def test(str: String): String = 
    {
     if (str.startsWith("if")) str else "if " + str
    }
     
   def main(args: Array[String]): Unit = {
      println("Result: " + test("if else"));
      println("Result: " + test("else"));
    }
}
