When tackling the problem on the second page, the scientists faced another challenge: the manuscript was difficult to read. Professor Burunkin determined that to improve readability, the manuscript text should undergo three sequential transformations:

1. Eliminate all line breaks from the text.

2. Substitute every occurrence of "<BR>" with a line break.

3. Continuously remove any occurrence of "<*>", where "*" represents any sequence of characters (including an empty sequence) that does not contain the characters ">" or "<", until no more such patterns exist.

He also demonstrated that regardless of the sequence in which step 3 is applied, the final text will always be the same. Assist the scientists in making the manuscript readable.
