Tips required from algorithm practitioners on how to learn algorithms

Hello,
I am trying to improve my programming skills and more particularly my proficiency at algorithms.
I decided to start with advanced sorting algorithms such as the quick sort and shell sort.
Here is what I did in order to practise:
-Working with a sample of data (array of integers) I started with going through the pseudo-code and manually applying each of the sort algorithms to the data with a sheet of paper in order to better understand those two algorithms.
-Then I tried to code the algorithms in java (without looking at the code in my book of course) in Netbeans.
Do you see other types of exercises (for now only about sorting algorithms as I will move to other algorithms later on) I could practise on in order to become more proficient?
Best regards,
J.

Sounds good.
Only other thing is try different sets of data. And try a really large set of data. Say 10,000 items. Just figuring out how to create that set can prove benefiicial.

How requirements from SOP are transferred to Demand Management

How requirements from SOP are transferred to Demand Management? what is transaction code for it ?
Madan S. Rode

Hi,
In mc82 view, after checking the capacity situation(By choosing view, capacity situation, show) you can check the load for that particular resource. Once the load is 100 %. You can save it.
Use mc78, copy the inactive version no to active no. (a00).
Then in mc82 view, go to Extras,
transfer to demand management,
Choose the strategy as LSF/VSF... according to your scenario & then click transfer.

How to export testcases/scenarios/requirements from OTM repository/folder?

Hi Folks,
Is there any provsion to export testcases/scenarios/requirements from OTM repository/folder?
Edited by: OATS Explorer on Feb 20, 2012 5:55 AM

Hi Sree,
You can export details of test, requirements etc to an excel file from the Reports tab. You can create your own report with your choice of fields and then export. The Win32 Test Manager client gives you the option of exporting a Project to xml.

Welcome to the Apple Community.
You can purchase Lion from the Mac App Store. You will need to meet the requirements for Lion, but the Mac App Store will tell you whether your Mac is capable of running Lion or not.

Requirement from other plant.

Hi Gurus,
There are plants A and B. Plant B is in need of service parts. Plant A is also not having stock for same parts then creates Purchase order for some vendor and corresponding requirement is triggered in plant B with reference as Procurement should be carried out in plant B. Plant B then purchase required parts for plant B. How this scenario can be mapped in SAP. Is there any way to map this? Please guide with detail steps.
Regards,
Pradeep

Hi
You can do that with the help of special procurement key in SAP. You need to define your own special procurement key for your plant in t.code OPPQ. Give your plant. Then click in special procurement. Create new entries.Give procurement type F and tick with draw from alternate plant or other options as per your requirement. Then Then assign it in masterial master for the required masterials. So that requirements in one plant is reflected in other plant.

Yosemite and minimum operating requirements from installers

After migrating from an iMac to a Macbook Pro, both running Yosemite, I am getting messages about the operating system not meeting minimum requirements from two different installers. One says I need 10.7, the other says 10.4. I am running 10.10. Both programs ran fine on the iMac before migrating to the MBP. What go lost in the move and how can I remedy? Also, why do he installers, from two different companies, not 'see' that I'm running 10.10? Thank you.

Hi Toshniwal,
Collecting project requirements from a client is more art than science. Yes, you can follow a template or checklist, but the information you really need comes from understanding the true benefits of the project. If you don't know, find out.
When you understand WHY a project is undertaken, then the questions you need to ask will follow logically. And, if you know WHY, then you will know which business processes are affected, and that most importantly, will lead you to the correct questions to ask.
In the past I have used a very simple rule...3P (People, Paper, Processes). You can call it 4P today (People, PC, Paper, Processes) to help with collecting requirements.
My requirements questions then fall into these categories.
People - Who interacts with Whom? How often?
Paper or PC - What data is passed by paper or electronically by PC? Which data is absolutely required? Which is nice to have? Which data, if missing, would cause significant financial failure or significant process failure?
Process - What triggers an event by People or Paper or PC? How many entry points are there into the process? How many exit points are there? At which point in the process is the data manipulated or transformed? What is the most important sub-process or integration process?
The above is not nearly all the questions I would ask, but merely a sample.
And, never rely on 1 source for all of your information. Make certain you have validated the requirements with multiple inputs from colleagues and client personnel.

Kent Bettisworth

I want to remove all of my photos out of iPhoto there are approximately 35000 some imported from an old hard drive and a SD Card from my Nikon D500 how do I do this

I want to remove all of my photos out of iPhoto there are approximately 35000 some imported from an old hard drive and a SD Card from my Nikon D500 how do I do this?
I have iPhoto version 9.1.5 (615)
Mac OS X version 10.6.8
I want to do this because when I imported from my old hard drive there was an error message stating that 12 photos were not imported as the programm did not recognise the format even though they were jpegs like the other photos in that particular album. The dates of the photo folders are wrong I have multiple copies of photos and every time I start iPhoto I get the following message 12 photos have been found in the iPhoto library that were not imported would you like to import them No or Yes
if you press Yes the same message comes back again and if you press Yes again the program flicks to last import for 2 seconds and then opens events.
if you press No the message The photos have been placed in the folder/user/judith/pictures/iphoto Library recovered photos then if you press OK the original message 12 photos have been found.............
if you press No at this point the message The photos have been placed in the folder/user /judith/pictures/iphoto Library recovered photos_11 the end number goes up by 1 every time you go through this process
Any help would be greatly appreciated

Did you import an iPhoto Library from the old Hard Drive? Do you still have that old Library?
The way to clear out a Library is to Export the photos - Apps like iPhoto2Disk or PhotoShare will help you export to a Folder tree matching your Events.
For the annoying start-up message:
Go to your Pictures Folder and find the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.
Look there for a Folder called 'Import' or 'Importing'.
Drag it to the Desktop. *Make no other changes*.
Start iPhoto. Does that help?
If it does then look inside that folder on your desktop. Does it contain anything you want? If not you can trash the folder.

Hi,
I want to load a sales order from XML file. How can I do ? how can i create the sales order?
what are the necessary setting for create the sales orders.

Prakesh.

Three options come to my mind.
Option 1: Use SAP transaction SXDA_TOOLS (Object Type BUS2032), Program Type (BAPI) and Program (CREATEFROMDAT2).
Option 2: Use SAP transaction SXDA_TOOLS (Object Type BUS2032), Program Type (DINP) and Program (RVINVB10).
Option 3: Translate the xml to IDoc so that ORDER04 / ORDER05 Idoc can be used to create Sales order (WEDI transaction).
