How to arrange in alphabetical order

Hi
I have a SplayTree , actually you can just say I have a tree for that matter, and there is a String on each line, and I need to print all this out in alphabetical order. I can't use an array since there is huge databse to be arranged in alphabetical order, so what kind of algorithm I can use to put all these words in alphabetical order? The functions I have access to in this Tree are insert, remove, find(returns a BinaryNode), makeEmpty, isEmpty(returns a boolean) and a printTree which returns nothing. So please tell me how to arrange all these in alphabetical order? I am able to print out the entire tree but without the order! Thanks a ton!

Why is it that you dont use one of the built in structures like a LinkedList to help you out? Also, if the data is coming from a DB why not do an order by on your query?
The fastest sort algorythim to use will be the Quick sort. If you look at the demos that come with java there is a sort demo that has this as one of the three examples and you could pull it right from Sun's code.
If you could even temporarily use something like a LinkedList then you could use the java.util.Arrays class to help you.

  • I created four (4) similar two (2) page file tables as an inventory of the contents of four (4) file crates full of LP vinyl record albums. How can these four (4) files be merged into a single file, then arranged in alphabetical order (by artist)?

    I am using "pages" version 5.5 (2109) as updated in its newest version after installing Yosemite OS X 10.10 on my 21.5 inch Mac desktop computer. When I printing the second file as a two sided document on a single sheet of paper, it only printed the first side. I looked at the copy of the file on my screen, and saw that the second page was also blank on my screen. I opened the original locked version of the 68 row, 4 column table, and found that both pages, 34 rows on each page, were intact, but when I saved it again, locked it, and reopened a duplicate copy, the second page again was not there. I ended up printing a copy of the original file, but I am nit able to save more than one page of the two page original. I would like to do this so I can edit the list without altering the original.                                                 I would eventually like to merge all four tables into one document, than arrange the entire merged file in alphabetical order. I would like to do this and have not been able to. This was the original question I had before I lost the second page of the second file table.

    In general theory, one now has the Edit button for their posts, until someone/anyone Replies to it. I've had Edit available for weeks, as opposed to the old forum's ~ 30 mins.
    That, however, is in theory. I've posted, and immediately seen something that needed editing, only to find NO Replies, yet the Edit button is no longer available, only seconds later. Still, in that same thread, I'd have the Edit button from older posts, to which there had also been no Replies even after several days/weeks. Found one that had to be over a month old, and Edit was still there.
    Do not know the why/how of this behavior. At first, I thought that maybe there WAS a Reply, that "ate" my Edit button, but had not Refreshed on my screen. Refresh still showed no Replies, just no Edit either. In those cases, I just Reply and mention the [Edit].
    Also, it seems that the buttons get very scrambled at times, and Refresh does not always clear that up. I end up clicking where I "think" the right button should be and hope for the best. Seems that when the buttons do bunch up they can appear at random around the page, often three atop one another, and maybe one way the heck out in left-field.
    While I'm on a role, it would be nice to be able to switch between Flattened and Threaded Views on the fly. Each has a use, and having to go to Options and then come back down to the thread is a very slow process. Jive is probably incapable of this, but I can dream.

  • How to put in alphabetical order the favorite phone numbers?

    My favourite phone numbers aren't in alphabetical order! Could I get a solution for this problem? Could someone help me?
    Thanks.

    This is really lame.  The favorites list should automatically be sorted by something other than when it was added to the list.  In my old Android OS it was sorted by contact name.  Android has many other problems and I like my new iPhone but this makes searching for a contact in this list more difficult and sorting manually entry by entry is not an adequate answer to the issue.

  • How to arrange month in order in cross tab in crystal report

    Hi all,
          we are using cross tab to arranging the data (month wise)  in crystal report. we have month in string format like jan2008. this field is in column of the cross tab. now we need to arrange the month in sorted order. At Present , the month is displayed as april2007, arpil2008, april2009,may 2007, may 2008, may 2009.
      now i want in this order. april 2007, may 2007, april 2008, may 2008, april 2009, may 2009. how to achieve this in crystal report.
    Regards,
    Shanthakumar.

    Try this,
    Create a new formula
    For example, "April 2009" is stored as string in {TABLENAME.FIELDNAME}
    datevalue("1 "&{TABLENAME.FIELDNAME});
    Now you have a date, composed of your year, your Month and 1.
    you can use it to order your data by date.
    If sometimes there is no blank between month and year ("April2009") try this
    local stringvar x;
    x:={TABLENAME.FIELDNAME} ;
    x:=left(x,length(x)-4)&" "&right(x,4);
    x:=replace(x,"  "," ");
    datevalue("1 " & x);
    regards,

  • How to disable the alphabetical order in lists in 8.5

    I have just installed LabView 8.5.
    I found that the lists of controls and globals are now ordered alphabetically in drop down boxes.
    I was using the tabing order to regroup items corresponding to the same functions.
    Is there an option to changed the order back to what it was before?
    Cheers
    Etienne

    Hi there,
    This was an intended feature for the Local and Global variables.  We decided to implement this feature as an improvement to the usability of Local and Global variables in LabVIEW and I'm afraid that this is not a customizable feature.
    You'll actually find that it is now possible to use the keyboard keys to skip to the appropriate local variable name in the list and if you have a very large list you can also use page up and page down.
    However if you are utilizing the Local and Global variables this much you may want to reconsider your application architecture.  Local and Global variables are the main reasons for race conditions and problematic code.  I would consider other methods to pass data from one section of code to another.  For example, Functional Global variables.
    Thanks

  • How can I keep my albums in iPhoto arranged in the order of my preference - alphabetically? Once arranged, iPhoto periodically rearranges them.

    How can I keep Albums in iPhoto in the order in which I arrange them? iPhoto periodically rearranges them in seemingly random order.

    Have iPhoto '11. Several times I have arrangged the Albums in alphabetical order. Perhaps "periodically rearrange" isn't the correct terminology, but if not the next time I open iPhoto then the 2nd or 3rd or 4th or..., the albums are in a different order, non-alphabetical. This was not a problem in the last iPhoto version.

  • When starting my MAC on the home page with my icons--  how do I arrange icons alphabetically left to right

    How does one arrange icons from left to right ala Windows.  I would like the Mac disk icon in the upper left of the window followed by app and file icons to appear in alphabetical order from left to right.  I know it will go vertically and then to the next row.  I have been reading English like this for over 60 yrs and the default set-up gives an old man a large pain in the head.  Any help would be greatly appreciated.
    Thank you,
    Jim Buckley

    I think they do it to be a pain in the ***. There is no reason to have people read in reverse alpha order.  Some countries read right to left but here it's reversed. You think the geniuses  here would figure out how to make allowance for that in their software.
    I love the mac mini's size, etc, but using mac in general has made me nuts. I don't understand how people think it's intuitive. I find myself taking a ridiculous amount of steps to get anything done, but it may just be me. I know some people just love them.
