Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

As per Jeff's suggestion in this comment:

You can use this question as a formatting sandbox. You can

  • edit this question itself (Community Wiki questions such as this one require 100 reputation to edit)
  • post answers to this question (Since this question is protected, this requires earning 10 reputation on this site)
  • post comments to this question or its answers
  • test suspected bugs with the editor

Beware that since the changes to syntax highlighting in December 2010, and the inline hints added March 2011, no syntax highlighting is applied unless the question's tags or an inline hint enable it. So, to test highlighting here in the sandbox:

  1. On the start of a line, specify a language inline using <!-- language: lang --> hints, and indent the code 4 spaces as usual. There is a full list of hints (scroll down a little).

    <!-- language: lang-html -->
    
        While not hinted otherwise: <html></html> source <b>goes</b> "here".
    
    <!-- language: lang-js -->
    
        var a = 3;
        while (not (a > 0)) {
            alert("JavaScript code <b>goes</b> here.");
        }
    
  2. Or:

    • Save your post.

    • Use something like Firebug (Firefox), Web Inspector (Safari, Chrome) or Developer Tools (Internet Explorer 8) to edit the resulting HTML. To open Chrome Dev Tools, press F12

    • Find the <pre> element and add the attribute class="prettyprint", or change it into something more specific, like class="lang-vb prettyprint".

    • Run the following in the location bar: javascript:prettyPrint();

@humn instead of a rollback, you can perform an edit with the exact same contents as before your edit (title, in your case) and assuming you do it within the 5 minutes grace period, it will show only a single revision with "[Edit removed during grace period]" - instead of having two revisions. – Shadow Wizard Apr 10 at 10:12

(TESTING LONGER ALL-CAPS ANSWER THAT MIGHT NOT TRIP BOT QUALITY FILTER)

FIRST, LOOK AT THE WHOLE PROGRAM

10 N=2000
20 PRINT "ARMSTRONG NUMBERS"
25 PRINT "BETWEEN 1 AND 2000"
30 PRINT
40 FOR 1=1 TO N
50 S=O
60 K=I
70 Q=INT(K/10)
80 R=K-10*Q
90 S=S+R*R*R
100 K=Q
110 IF K<>O THEN 70
120 IF I<>S THEN 130
125 PRINT I
130 NEXT I
140 END 

FIRST, WE INITIALIZE THE VARIABLE "N" TO 2000, THEN WE PRINT SOME INTRODUCTION TO THE USER. NEXT, THERE IS FOR-LOOP FROM 1 to N (2000). THE LOOP IS DOING IT'S JOB WELL DONE, UNTIL IT REACHES LINE 110. SOMETIMES IT LOOPS, SOMETIMES IT DOESN'T, BUT ANYWAY IT MAY LOOP FROM 70 TO 110. THIS IS ACTUALLY A WHILE-LOOP THAT WILL STOP AFTER "K" IS EQUAL TO "O" (DON'T ASK ME WHY). NEXT, IF "I" IS EQUAL TO "S", THEN IT'S AN ARMSTRONG NUMBER, SO IT WILL BE PRINTED ON THE MONITOR. OTHERWISE, IT WILL BE SKIPPED AND CHECK THE NEXT NUMBER.

This is a test to try out grace period editing.

Due to new logic, the grace period ends if a new comment is added. But what happens if that comment is deleted?

Edit Log

v1 - #1 - Initial Post
v1 - #2 - Edit in grace period (normal)
v? - #3 - Edit after comment added by another user and deleted

So the conclusion is that a comment will stop ninja edits, but only if they are around.

I find it hard to believe, with the amount of rep that you have, that you would consider simply linking to another question is all it takes to make a good answer?

If your answer to question A can be used in question B, that suggests that B is a duplicate of A and can be closed as such.

If they are not duplicates, then you should be answering the question. Tailor your code to answer the actual question asked.

It has been well established that answers which contain nothing more than links will likely be deleted. They may be converted to comments, or they may not. There are plenty of related discussions here.

$VAR1 = { 'P5' => {   'E' => '06' => [100, 200, 95] 'B' => '23' => [20, 1000, 05, 30]   },   'P2' => {         'C' => '24' => [18, 23, 2300, 3456]   },   'P1' => {         'A' => '12' => [24, 25, 3200, 5668]         'D' => '15' => [168]       } };
