Solve: Last Chars

/ Adapted from CodingBat

Given 2 Strings, first and second, return a new String made of the first character of first and the last character of second. So "yo" and "kotlin" yields "yn". If either string is length 0, use '@' for its missing char.

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 lastChars(
  first: String,
  second: String,
): String {
  return "" // You may need to remove this starter code
}
