Q: BubbleSort - checking if bubblesort is decreasing the iterations through the array

nat1What i'm hoping my code is doing is instead of making 99 comparisons on every pass of a 100 element array, it will now make 98 comparisons on the second pass, 97 on the third pass and so on and thus decreasing the iteration through the array. Here's my code st.Reset(); st.Start(...

A: Create a new object class or write a method which converts sub-class objects? or something else? Performance NOT Preference

Simon ForsbergToo many subclasses Neither of these approaches are very good, as both of them have more subclasses than necessary. Why does EightsCard extend Card ? What if you wanted to implement some other card game? (There are quite a few, you know...) Would you make one subclass for each card game? Please ...

What is it doing when it's running so slowly? (Use F8 to step through the code to find out.) What does it do when it fails? Errors? Where? How is this called? An event or where?

Which this is nice, this is the second time someone has been confused by it. :)
 
Why would the cat break your PSU?

@SimonForsberg Could you change the status of this question from to completed, by-design or whatever is used to indicate no work has to be done?

@Mast Done.
I bet there's a whole bunch of meta's that could have a status on them.
 
@SimonForsberg Probably, although a whole bunch of them are in the 'nice idea, but the chance of it happening is less than 1%' phase. Wouldn't know what status to put on that.
'declined' could work...
[feature-request] -[status-bydesign] -[status-completed] -[status-declined] returns 90 questions.
Admittedly, that's including duplicates.
[feature-request] is:q -"[duplicate]" -[status-bydesign] -[status-completed] -[status-declined] 83 questions

Quick question: Does rolling back an edit trigger the post to be added to the reopen queue? (asking for this post where the post content was removed shortly before closure: codereview.stackexchange.com/questions/195278/…)
 
6:56 PM
@FreezePhoenix ^^
@Graipher Good question, I don't think it does but I'm not sure.
A rollback is a special kind of edit after all.
In this case however, just leave it be and let the question be removed.
 
@Mast Ah yes, just saw in the timeline that it already has one delete vote (not quite there yet where I can cast those...)
