 A list of invariants for the transform function:
 \begin{itemize}
     \item bp is increased by one for every opening brace or bracket and goes down by one for every closing brace or bracket. (this gets violated)

 \end{itemize}
 The change that needs to be made is to make sure that bp decrements when there is an opening curly brace regardless of the rotate amount.
