I need to state the big o of the following fragment: sum =0; for (int i=1; i<n; i++) { for (int j=1; j< n/i; j++) { sum = sum +j; } } I know the outer loop is O(n) but I am having a problem analyzing the inner loop. I think it's O(log n). I would appreciate any help. Thank you in advance. ...
I have a C# project for which I need to find the all private methods which are not called from any other public method directly or indirectly. In addition, for each private method which is called from a public method, I need to know which public method it is. Then I will detemine if that method is really called from a client of the clas...
Does anybody know a minimalistic, nice-looking visitor statistics suite based on PHP that displays visitor stats in a end-user friendly way. I know Google Analytics, and the big names in PHP and Perl based traffic analysis; they are all too complicated and feature-rich for what I need. I am looking for something that is already totally ...
I was wondering if any analysts/architects have a solution for the hundreds of CRUD operations I would have to add to nearly every class in my UML diagram. Do you let each class inherit from a base class that implements the CRUD operations? Best practices and design patterns about this are very much appreciated! ...
I'd like to know the best way to deep dive into the flow of my users. For example, I have 4 pages in my flow, how can I analyze which users abandon on which step? I can definitely do it by hand with logging, etc, but I'd rather use an off the shelf solution. I have apache request logs, as well as google analytics. Can these analyze user...
For my startup, I track everything myself rather than rely on google analytics. This is nice because I can actually have ips and user ids and everything. This worked well until my tracking table rose about 2 million rows. The table is called acts, and records: ip url note account_id ...where available. Now, trying to do something ...

According to the IFPUG manual, the menu is not counted. However, if we can perform some functions, which do not invoke a dialog, via the menu, then...
Hello everyone. I want to write a java program that searches through a cipher text and returns a frequency count of the characters in the cipher, for example the cipher: "jshddllpkeldldwgbdpked" will have a result like this: 2 letter occurrences: pk = 2, ke = 2, ld = 2 3 letter occurrences: pke = 2. Any algorithm that allows me to ...
Hi, i have an algorithm that searches into a directory and search for all the text files in that directory and any sub-directory. Assuming i do not know how many sub-directories and sub-sub directories there are in the parent directory. how do i calculate the complexity? this is the code i am using public List<string> GetFilesInDirec...
It's a well-known isssue with Quicksort that when the data set is in or almost in sort order, performance degrades horribly. In this case, Insertion Sort, which is normally very slow, is easily the best choice. The question is knowing when to use which. Is there an algorithm available to run through a data set, apply a comparison fact...
I'm looking to get the trace logs for AS (same stuff as for SQL server) in real time. I can't find any .net interfaces to this stuff. So far the only realistic solution I can think of is to run it permanently and have it dump to a new table which I listen to on updates via triggers. Does anyone know of a better way of doing this? This ...

Hi I am looking for a software which is able to decompose and analyze files. Do you know any? What I mean is something that, given a file, would tell me for example: here is the magic number telling that it is a PNG, and here starts a colors definition, here goes the compression flag, and then there are the picture data, and so on......

I am comparing two algorithms, Prim's and Kruskal's. I understand the basic concept of time complexity and when the two work best (sparse/dense graphs) I found this on the Internet, but I am struggling to convert it to English. dense graph: Prim = O(N2) Kruskal = O(N2*log(N)) sparse graph: Prim = O(N2) Kr...
Hi all I wanna to draw a business use case diagram for a specified problem. The problem has some rules. Now I wanna to ask that: Is it correct to put business rules when drawing business use case? ...
