  • How to compute palindrome from a stream of characters in sub-linear space/time?

    - by wrick
    I don't even know if a solution exists or not. Here is the problem in detail. You are a program that is accepting an infinitely long stream of characters (for simplicity you can assume characters are either 1 or 0). At any point, I can stop the stream (let's say after N characters were passed through) and ask you if the string received so far is a palindrome or not. How can you do this using less sub-linear space and/or time.

  • Is there a java api to access bugzilla?

    - by Mauli
    Is there a (standalone!) java api which wraps the XML-RPC interface to bugzilla? I don't want to program my own api for it, and I can't actually find a library which does this (and only this). Update: I'm looking for something like this http://oss.dbc.dk/bugzproxy/ only written in Java

  • How to find if dataTable contains column which name starts with abc

    - by VilemRousi
    In my program I have a dataTable and I´d like to know if is there a column which name starts with abc. For example I have a DataTable and its name is abcdef. I like to find this column using something like this: DataTable.Columns.Constains(ColumnName.StartWith(abc)) Because I know only part of the column name, I cannot use a Contains method. Is there any simple way how to do that? Thanks a lot.

  • Warning: pointer of type 'void *' used in subtraction

    - by idealistikz
    Although it runs correctly, the following results in the aforementioned compiler warning: return ((item - (my->items))/(my->itemSize)); 'item' is a 'void *'; 'my-items' is a 'void *'; 'my-itemSize' is an 'int' Casting 'item' and 'my-items' as an 'int *' caused the program to run improperly. What is the best way to remove the warning?

    - by William
    Is there a good J2ME IDE? I mean something lightweight, and portable. Something that can run what you program on it. My favorite Java IDE is JCreator Lite. Is there something like that for J2ME? Also, which would you say is the best J2ME IDE?

  • Function allocation

    - by novice_coder
    Where are functions stored in a C++ program? For example int abc() { //where am I stored? } I know that we can take the address of a function, that means functions are stored somewhere in memory. But I have already read at many places that no memory allocation for functions takes place. I am confused. My question may seem vague to many of you but I can't help.

  • Why do all procedures have to be defined before the compiler sees them?

    - by incrediman
    For example, take a look at this code (from tspl4): (define proc1 (lambda (x y) (proc2 y x))) If I run this as my program in scheme... #!r6rs (import (rnrs)) (define proc1 (lambda (x y) (proc2 y x))) I get this error: expand: unbound identifier in module in: proc2 ...This code works fine though: #!r6rs (import (rnrs)) (define proc2 +) (define proc1 (lambda (x y) (proc2 y x))) (display (proc1 2 3)) ;output: 5

  • How does JVM handles dynamic allocation

    I want to understand how JVM manages heap for the dynamic allocations. Since every java program is invoked as a thread, when does JVM's garbage collector come into play. Also, how things work for javascript's dynamic allocation ?

  • How can I connect to MSMQ over a workgroup?

    - by cyclotis04
    I'm writing a simple console client-server app using MSMQ. I'm attempting to run it over the workgroup we have set up. They run just fine when run on the same computer, but I can't get them to connect over the network. I've tried adding Direct=, OS:, and a bunch of combinations of other prefaces, but I'm running out of ideas, and obviously don't know the right way to do it. My queue's don't have GUIDs, which is also slightly confusing. Whenever I attempt to connect to a remote machine, I get an invalid queue name message. What do I have to do to make this work? Server: class Program { static string _queue = @"\Private$\qim"; static MessageQueue _mq; static readonly object _mqLock = new object(); static void Main(string[] args) { _queue = Dns.GetHostName() + _queue; lock (_mqLock) { if (!MessageQueue.Exists(_queue)) _mq = MessageQueue.Create(_queue); else _mq = new MessageQueue(_queue); } Console.Write("Starting server at {0}:\n\n", _mq.Path); _mq.Formatter = new BinaryMessageFormatter(); _mq.BeginReceive(new TimeSpan(0, 1, 0), new object(), OnReceive); while (Console.ReadKey().Key != ConsoleKey.Escape) { } _mq.Close(); } static void OnReceive(IAsyncResult result) { Message msg; lock (_mqLock) { try { msg = _mq.EndReceive(result); Console.Write(msg.Body); } catch (Exception ex) { Console.Write("\n" + ex.Message + "\n"); } } _mq.BeginReceive(new TimeSpan(0, 1, 0), new object(), OnReceive); } } Client: class Program { static MessageQueue _mq; static void Main(string[] args) { string queue; while (_mq == null) { Console.Write("Enter the queue name:\n"); queue = Console.ReadLine(); //queue += @"\Private$\qim"; try { if (MessageQueue.Exists(queue)) _mq = new MessageQueue(queue); } catch (Exception ex) { Console.Write("\n" + ex.Message + "\n"); _mq = null; } } Console.Write("Connected. Begin typing.\n\n"); _mq.Formatter = new BinaryMessageFormatter(); ConsoleKeyInfo key = new ConsoleKeyInfo(); while (key.Key != ConsoleKey.Escape) { key = Console.ReadKey(); _mq.Send(key.KeyChar.ToString()); } } }

  • Does a lazy-programmer file auto-generator tags exist?

    - by Anthony Forloney
    I was wondering (if possible) if there was a program/tool/utility that when I create a new file and provide it with an extension that it creates the tags automatically? For example, a new file I create called index.php would have the appropriate tags auto-generated inside: <?php ?> I hope you get the idea. Does one, or could one, exist, preferably Windows based? Any information regarding this would be helpful.

  • How do I get parameters between activities?

    - by Matt
    I am working on an app that has multiple tabs. In the first tab the user will enter values. In the other tabs it will display the results of calculations based off of those values. Like in tab 1, the user will enter "3" and "2". In tab 2, the program will add them and display "5". In tab 2 how do I access the ints "3" and "2"? Thanks

  • Visual Studio Generating Code in Release mode

    - by bball
    I am using Visual Studio to compile some C++ Code. When I compile my program in Debug mode it works perfectly, but when I try compiling it in Release mode, VS halts when Generating Code (ie: took 20 mins and still didn't finish). After I forced VS to stop the build process, the executable generated was huge 2MB while it should be about 304KB. Please can you help figure this out. How should I setup the configuration parameters for Release mode to work? Thanks,

  • Anyone have experience developing with ESQL/C for INFORMIX-SQL?

    - by Frank Developer
    Does anyone have experience developing with ESQL/C for INFORMIX-SQL, as in calling C funcs within "Perform" screen generator and "ACE" report writer? I have ISQL without ESQL/C. I experimented compiling a perform screen, where in the instructions section I put "ON BEGINNING CALL userfunc() END" and although I don't have ESQL/C, the Perform screen successfully compiled without errors!.. Apparently, the compiler didn't reject the C call even though there's no ESQL/C or C program linked.
