#42Document Formatting Parser

A document-processing system receives text containing nested formatting blocks. Each pair of parentheses represents a formatting block whose contents must be processed in reverse order.

For every matching pair of parentheses, reverse the text inside that block. Nested blocks are processed from the innermost block outward.

After all formatting blocks have been processed, return the final document text without any parentheses.
