Solve: Without 2

Given a String, if a length 2 substring appears at both the beginning and end, return a String without the substring at the beginning. So "HelloHe" yields "lloHe". The substring may overlap with itself, so "Hi" yields "". Otherwise, return the original string unchanged.

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 without2(str: String): String {
  return "" // You may need to remove this starter code
}
