I am doing a SPOJ problem called MBALL - http://www.spoj.com/problems/MBALL/ - it is similar to the coin change problem where you are asked for the number of ways you can make a certain amount of cents. In the case of the problem it is the number of ways you can make a certain score playing Mouse...
We currently have two Meta tags regarding community challenges:
weekend-challenge (8 questions)
code-challenge (1 question)
The main site equivalent of these tags are also synonymized, which will eventually be done here as well. However, does it make sense to also synonymize them with a new ...
It started with weekend-challenge, in this post (the rock-paper-scissors-lizard-spock challenge). Then it was used pretty much every week of December 2013 when a new meta post came up for voting on what the next challenge should be.
Then we "rebooted" the thing after taking a break, and since it...
I need to match all of these opening tags:
<p>
<a href="foo">
But not these:
<br />
<hr class="foo" />
I came up with this and wanted to make sure I've got it right. I am only capturing the a-z.
<([a-z]+) *[^/]*?>
I believe it says:
Find a less-than, then
Find (and capture) a-z one or ...
Iterate through the entrySet like so:
public static void printMap(Map mp) {
Iterator it = mp.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pairs = (Map.Entry)it.next();
System.out.println(pairs.getKey() + " = " + pairs.getValue());
it.remove(); // avoids...

Is it okay to edit the question to include the improved code?
I would like to do so for the following reasons:
To share the improved code with others
To show the answering persons that I take their feedback seriously
To make sure that I understood (and implement) the feedback in the right mann...
As your code doesn't really work and I got quite interested by this problem : I took mjolka's precious comments into account.
Re-adapting code from the link in his comment, here what I got :
public class MirrorString {
/* Returns length of longest common substring of X and Y */

I suggest we take on the challenge of finding the worst code out there on our sister sites, and making it the best!
...I think you guys overcomplicate things a lot. This should work just dandy:
DELETE FROM
