Given a String return the String made of its first two chars. So the String "Hello" yields "He". If the string is shorter than length 2, return whatever there is, so "X" yields "X", and the empty string "" yields the empty string "".

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