    - by user2738718
    package practise; public class Node { public int data; public Node next; public Node (int data, Node next) { this.data = data; this.next = next; } public int size (Node list) { int count = 0; while(list != null){ list = list.next; count++; } return count; } public static Node insert(Node head, int value) { Node T; if (head == null || head.data <= value) { T = new Node(value,head); return T; } else { head.next = insert(head.next, value); return head; } } } This work fine for all data values less than the first or the head. anything greater than than doesn't get added to the list.please explain in simple terms thanks.

  • How to determine whether or not a video format is supported

    - by Tal Even-Tov
    Hi, I've had to write an application that lists and plays tutorial videos along with accompanying text. It works well but since the videos are added by the user I need a way of checking to see whether or not a video can be played on the machine. I'm not sure whether or not there is an easy way to try test the file (and catch errors) or if I need to start looking at codecs installed. Does anybody have any experience with this?

  • Format decimal to currency, should be in cents for values $0 to $1

    - by Spongeboy
    I have a decimal variable which represents a donation amount. Currently I am displaying it on screen as a currency like so- DonationAmount.ToString("C"); This gives the following output (given a US locale) 1 -> $1.00 2 -> $2.00 0.5 -> $0.50 I am happy with the first two example, but want to have "0.5" show as "50c". My current solution is with a conditional- if (DonationAmount > 1) return (DonationAmount * 100m).ToString() + "c"; else return DonationAmount.ToString("C"); Is there a better way?

  • Best ways to format LINQ queries.

    - by Aren B
    Before you ignore / vote-to-close this question, I consider this a valid question to ask because code clarity is an important topic of discussion, it's essential to writing maintainable code and I would greatly appreciate answers from those who have come across this before. I've recently run into this problem, LINQ queries can get pretty nasty real quick because of the large amount of nesting. Below are some examples of the differences in formatting that I've come up with (for the same relatively non-complex query) No Formatting var allInventory = system.InventorySources.Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }).GroupBy(i => i.Region, i => i.Inventory); Elevated Formatting var allInventory = system.InventorySources .Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy( i => i.Region, i => i.Inventory); Block Formatting var allInventory = system.InventorySources .Select( src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy( i => i.Region, i => i.Inventory ); List Formatting var allInventory = system.InventorySources .Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy(i => i.Region, i => i.Inventory); I want to come up with a standard for linq formatting so that it maximizes readability & understanding and looks clean and professional. So far I can't decide so I turn the question to the professionals here.

  • Programatically convert complex Excel file into HTML format

    - by shuby_rocks
    Hello all, I have a set of complex Excel files (with figures in it) that I want to show in a web browser. So I need to convert them into HTML page first. Since the excel files are very complex, I can not just parse them and generate a HTML table with HTML tags. The current manual solution that works fine is when I use Microsoft Excel software to save the spreadsheet as a HTML page. I want to automate this task in some way since I want to do it progrmatically through Java. Is their any existing solution or a way to do it? Thanks.

  • List tags with commits in the same format like git branch -v

    - by NickSoft
    Hi I would like to list tags like it's listed by: # git branch -v * devel e7f5e36 firxed bugs master 63e9c56 remove unused code without the * (you can't checkout tag). It would be good to have an option to list full or short SHA1. A bash script is also fine, but it would be nice to use git commands more and shell scripting less. I've read this question Git - how to tell which commit a tag points to and it helped me, but it's not all I want. Edit: I didn't know that annotated tags had SHA1. I wanted SHA1 of commits that tag points to, not the tags themselfs.

  • matlab's fortran's format equivalents

    - by ldigas
    What would be matlab's equivalent of write(1,'("Speed, resistance, power",3f8.2)')(a(i),i=1,3) I've tried a = [10. 20. 200.] fprintf(unit1,'a = 3%8.1e',a) but I'm still having trouble with it (the whole matlab output formatting thing). Edit for Kenny: for the values of a as given above, it would give (in a new row): Speed, resistance, power 10.00 20.00 200.00

  • WPF format displayed text?

    - by Mark
    I have a column defined like this: <DataGridTextColumn Binding="{Binding Path=FileSizeBytes, Mode=OneWay}" Header="Size" IsReadOnly="True" /> But instead of displaying the file size as a big number, I'd like to display units, but still have it sort by the actual FileSizeBytes. Is there some way I can run it through a function or something before displaying it?

  • Dividing a string into list according to the format given

    - by user506710
    Hello all , I have a string like "SAB_bARGS_D" . What I want is that the string gets divided into list of characters but whenever there is a _ sign the next character gets appended to the previous one. So the answer to above should be ['S','A','B_b','A','R','G','S_D'] It can be done by using a for loop traversing through the list but is there an inbuilt function that I can use..... Thanks a lot

  • use printf("text %d", number) type format to assign value to variable

    - by rksprst
    I would like to use the syntax that printf uses, using the %d, %s and adding values after to assign a value to a char[]. Is this possible? e.g. Given an output of: printf("now: %d-%d-%d %d:%d:%d\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec); I'd like to assign that to char[] output; How can this be done? I tried: sprintf(output, "now: %d-%d-%d %d:%d:%d\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec); but that didn't seem to work. Is sprintf used differently... or is that not what I should be using? Thanks!

  • Without width printing format in C

    - by yCalleecharan
    Hi, in C if I have a printf statement containing say "%.2f", it says that the precision is 2 digits after the decimal place. I haven't explicitly specify the width. I have two questions: Is this good programming practice?; Is without specifying the width means that the width of the field will get adjusted automatically when printing the number, irrespective of the number of digits it contains? Thanks a lot...

  • How do I choose a package format for Linux software distribution?

    - by Ian C.
    We have a Java-based application that, to date, we've been distributing as a tarball with instructions for deploying. It's mostly self-contained so deployment is fairly straight-forward: Untar on the disk you'd like it to live on; Make sure Java is in your path and a suitable distro and version; Verify ownership and group on all the files Start up the server processes with our start script If the user wants to get in to start-on-boot stuff with SysV we have some written instructions and a template init file for it in our tarball. We'd like to make this installation process a little more seamless; take care of the permissions and the init script deployment. We're also going to start bundling our own JRE with the application so that we're mostly free of external dependencies. The question we're faced with now is: how do we pick a package format for distribution? Is RPM the standard? Can all package management tools deal with it now? Our clients primarily run RHEL and CentOS, but we do have some using SuSE and even Debian. If we can pick a distro-agnostic format we'd prefer that. What about a self-extracting shell script? Something akin to how Java is distributed. If we're dependency-free would the self-extracting script be sufficient? What features or conveniences would we lose out on going with the script versus a proper package format meant for use by a package manager?

  • Existing parsers in c# (BSD license or similar)

    - by Sylverdrag
    I am looking for parsers (in C#) for a bunch of formats. (PHP, ASP, some XML based formats, HTML,...pretty much anything I can get my hands on.) The purpose is to separate the text from the code and do some edits without messing up the code. I had a look at ANTLR, but while it seems like the "right tool", there is just too much prior knowledge assumed. I have an easier time writing a parser from scratch than understanding how to "easily" generate parsers from ANTLR. (I wrote a small parser for a specific type of RTF files within a couple days, so the task is probably within my reach, but as I have no formal knowledge of parsing/lexing, I am at loss with ANTLR) Then it occurred to me that there must existing parsers for many formats, so before I start writing yet another a brand new and potentially buggy version of the wheel, I figured I would check what parsers already exist and can be reused in a commercial product. I could use parsers for just about every format in existence, so this question would be a good place to make a list of all existing free parsers written in C#, if there are any. Thanks in advance for your suggestions

  • Flex: convert VideoPlayer.currentTime to string "00:00:00:000"

    - by numediaweb
    Hi there! what about this one: I want to format the currentTime displayed by a videoPlayer component inside flex, something like : 8230.999 to something like 01:59:59:999 which is "hours:minutes:seconds:milliseconds" I trie different sets of codes but they can't get it to work because currentTime is nor a correct miliseconds time as it adds a floating 3 digit point to seconds; so instead of : 2000ms it outputs 2.000 something people like me just can't understand! thanx for any help :) ### UPDATE I still have problem with milliseconds. here's the current MXML: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ protected function convert_clickHandler(event:MouseEvent):void { var val:Number = new Number(inPut.text); //inPut.text = 1000.001 //val = val * 1000; outPut.text = timeFormat(val); } public static function timeFormat(value:Number):String { var milliseconds:Number = value % 1000; var seconds:Number = Math.floor((value/1000) % 60); var minutes:Number = Math.floor((value/60000) % 60); var hours:Number = Math.floor((value/3600000) % 24); var s_miliseconds:String = (milliseconds<10 ?

  • Weird response for controller.request.format.html? in Rails

    - by Tony
    In my main controller, I have this: class MainController < ApplicationController before_filter do |controller| logger.info "controller.request.format.html? = #{controller.request.format.html?}" logger.info "controller.request.format.fbml? = #{controller.request.format.fbml?}" controller.send :login_required if controller.request.format.html? controller.send :facebook_auth_required if controller.request.format.fbml? end As expected, I get "true" for the ...fbml? line if a request comes from Facebook (my facebooker gem automatically sets the format). However, I get "5" for the ...html? line if the request comes from Facebook. Why would a method with a ? ever return a "5"? Isn't that against Rails conventions? Also, I think "5" is considered true so this might mess up my filters. Still looking into that... Any ideas?
