Given a String and an int n, return a string made of the first and last n chars from the String. The String length will be at least n.

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.

String nTwice(String input, int n) {
  return ""; // You may need to remove this starter code
}
