Hello, any help appreciated with following problem. I figured out the
algorithm (I think), just having trouble proving it is optimal.
Suppose we are given n tasks each of which takes 1 unit time to
complete. Suppose further that each task has a deadline by which it
is expected to finish. IF a task is not finished by the deadline, a
standard penalty of $10 is applied. The problem is to find a schedule
of the tasks that minimizes the...

4.2.1 Regular Expression Syntax
http://docs.python.org/lib/re-syntax.html
*?, +?, ??
Adding "?" after the qualifier makes it perform the match in non-greedy or
minimal fashion; as few characters as possible will be matched.
the regular expression module fails to perform non-greedy matches as
described in the documentation: more than "as few characters as possible"

Hi. I really need help with a regular expression in ASP. I need a regex
pattern that will grab a select or textarea tag in an HTML file. If I run
the pattern I should get
<select name="whatever">
<option value="a" selected>A</option>
<option value="b">B</option>
<option value="c">C</option>
</select>

Hello,
I need to browse a list of hyperlinks, each followed by an
author, and remove the links only for certain authors.
1. I searched the archives on Google, but didn't find how to tell the
RegExp object to be non-greedy as using the ? quantifier doesn't seem
to work.

I want to match one or two instances of a pattern in a string.
According to the docs for the 're' module
( http://python.org/doc/current/lib/re-syntax.html ) the '?' qualifier
is greedy by default, and adding a '?' after a qualifier makes it
non-greedy.

the '*' and '+' don't seem to be greedy.. they will consume less in
order to match a string:
('aa', 'ab')
this is the sort of behaviour i'd expect from
'(a+?)(ab)'
a+ should greedily consume a's at the expense of the string not matching

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
