Given a String and an Int n, return a string made of the first n characters of the passed string, followed by the first n - 1 characters, and so on. So the String "Chocolate" with n = 4 yields "ChocChoChC". You may assume that n is between 0 and the length of the string, inclusive.

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 repeatFront(
  input: String,
  n: Int,
): String {
  return "" // You may need to remove this starter code
}
