Given a String, take the first 2 chars and return the String with the 2 chars added at both the front and back, so "kitten" yields "kikittenki". If the String length is less than 2, use whatever chars are there.

For this problem we're expecting only a method.

Don't define a class, include modifiers like static or public, add import statements, or add code outside the method declaration.

fun front22(input: String): String {
  return "" // You may need to remove this starter code
}
