Regular expressions

*?, +?, ??

The '*', '+', and '?' qualifiers are all greedy; they match as much text as
possible. Sometimes this behaviour isn’t desired; if the RE <.*> is matched
against '<a> b <c>', it will match the entire string, and not just '<a>'.
Adding ? after the qualifier makes it perform the match in non-greedy or
minimal fashion; as few characters as possible will be matched. Using the
RE <.*?> will match only '<a>'.

It says that the RE <.*?> matches only <a> but it also matches <c>

 I am also attaching the pdf document with the same content
