You’re asking a homework question so here are hints that I would give
someone who is struggling with homework.

Do you already know how to get the comment character of the current buffer?

Do you already know how to escape an arbitrary character for safe use
in a regexp?

Do you already know which part of the regexp you have is responsible
for matching three semicolons?

Do you already know how to concatenate strings?
