  • Passing 2D array with variable dimensions as function argument

    - by TheCrazyProgrammer
    I just saw the following code among the successful submissions at codechef. http://www.codechef.com/viewplaintext/1595846 I used to think that float max(int n,int arr[n][n]) {....} is not allowed in C++ (as 'n' is a variable). My CodeBlocks (on windows) with MinGW [gcc 4.4] gives compile time error. that "error: array bound is not an integer constant. Then how can be such a solution be accepted by CodeChef's judge. Is there any special flag that allows us to do that in C++??? EDIT: A link showing status as AC (accepted) : http://www.codechef.com/viewsolution/1595846

  • "this" in function parameter

    - by chris
    Looking at some code examples for HtmlHelpers, and I see declarations that look like: public static string HelperName(this HtmlHelper htmlHelper, ...more regular params ) I can't remember seeing this type of construct any where else - can someone explain the purpose of the "this"? I thought that by declaring something public static meant that the class did not need to be instantiated - so what is "this" in this case?

  • Need help in downloading file with header() function

    - by riccardo
    Hi. I'm trying to explain as best as I can, sorry for my English. I have a list of links, each linked to a php file with an id by parameters (ex. download.php?id=1 or ?id=2 and so on). This file create a new instance of a class witch return the correct header of the files so it displays the save dialog box of the browser. Now I need to check if the files is already downloaded in past (The first time you downloaded it I add a field on the mysql db). This checks go ahead if you haven't download the files, else return false. Here is the problem, when it returns false or something else the browser redirect me to the download.php file, so I get a blank page or what I'm echoing. I need that if the file is already download it show me a js alert for advice ppl. Hope you can understand what i mean. Thanks for help

  • Does Len function only evaluate numerical results?

    - by Mel
    Why does the following code not output "Error" if the form is submitted with a blank field? Does Len only evaluate numerical values? <cfif NOT Len(Trim("Form.myField"))> <cfoutput>Error</cfoutput> </cfif> The following also does not evaluate as expected: <cfif Len(Trim("Form.myField")) IS 0> <cfoutput>Error</cfoutput> </cfif> HTML: <input type="text" name="myField" value="">

  • Array of function pointers in Java

    - by Waltzy
    I have read this question and I'm still not sure whether it is possible to keep pointers to methods in an array in Java, if anyone knows if this is possible or not it would be a real help. I'm trying to find an elegant solution of keeping a list of Strings and associated functions without writing a mess of hundreds of 'if's. Cheers edit- 'functions' changed to 'methods', seems to bug people.

  • CodeIgniter Question: How to delete records using ActiveRecord with mySQL function as WHERE conditio

    - by Jhourlad Estrella
    I have a table named ChatSessions where I keep track of active users in the chatroom. I need to prune expired user sessions from the table every 10 minutes. Using pure php-mysql is plain simple but I'm totally clueless how to convert this into ActiveRecord in CodeIgniter. The plain SQL query is below: SELECT * FROM `ChatSessions` WHERE `SessionExpires` < DATE_SUB( NOW( ) , INTERVAL 10 MINUTE ) Can anybody tell me what is the equivalent code in CodeIgniter using ActiveRecord? Thanks in advanced.

For example: Suppose, first i have month selected as 02/2010 At this time the data in grid view is for exapmle 01234 now when i select month 03/2010 the data in grid changes to 56789 now when i click on back button, then data in grid changes to 01234 but the month in dropdown remains to 03/2010. Please help me for this.. Thanks in advance for all who will give solution for this.

  • Override l() function in Drupal

    - by Marco
    I'm currently working on a Drupal site (6.*), which when in production mode will be accessed through some kind of http proxy, which means I will have to rewrite all the links for my custom theme if the $_SERVER['HTTP_X_FORWARDED_SERVER'] variable is set to the domain people will access the site from. The site has a lot of internal linking, mostly through Views. My thought is that the easiest way to solve this would be to hook into the url() and/or the l() functions and post process the url before returning it if HTTP_X_FORWARDED_SERVER is set. My problem is that I can't figure out how to hook into these functions, or if it's even possible without touching the core, has anyone had to do this? How did you solve it?

  • A faster alternative to Pandas `isin` function

    - by user3576212
    I have a very large data frame df that looks like: ID Value1 Value2 1345 3.2 332 1355 2.2 32 2346 1.0 11 3456 8.9 322 And I have a list that contains a subset of IDs ID_list. I need to have a subset of df for the ID contained in ID_list. Currently, I am using df_sub=df[df.ID.isin(ID_list)] to do it. But it takes a lot time. IDs contained in ID_list doesn't have any pattern, so it's not within certain range. (And I need to apply the same operation to many similar dataframes. I was wondering if there is any faster way to do this. Will it help a lot if make ID as the index? Thanks!

  • created persisted computed columns when the user defined scalar function appears to be non-determini

    - by Ralph Shillington
    I have a scalar UDF that I know to be deterministic, however SQL doesn't. Is there a way to declare it as deterministic so that I can then use it in a persisted computed column definition? further clarification: The purpose of this exercise is that I need to harvest out specific values from an XML column on the row. I can't use the value method of the xml column in my computed column definition, but I can use it in a UDF. I know the xpath query in the value method will produce the same output give the same input so while I certainly understand that not all calls to value will be deterministic I want to assert that mine is.

  • Nested <ul><li> navigation menu using a recursive Python function

    - by Alex
    Hi. I want to render this data structure as an unordered list. menu = [ [1, 0], [2, 1], [3, 1], [4, 3], [5, 3], [6, 5], [7,1] ] [n][0] is the key [n][1] references the parent key The desired output is: <ul> <li>Node 1</li> <ul> <li>Node 2</li> <li>Node 3</li> <ul> <li>Node 4</li> <li>Node 5</li> <ul> <li>Node 6</li> </ul> </ul> <li>Node 7</li> </ul> </ul> I could probably do this without recursion but that would be no fun. Unfortunately, I am having problems putting it all together. I don't have much experience with recursion and this is proving to be very difficult for me to build and debug. What is the most efficient way to solve this problem in Python? Thanks!

  • Get information about a function in python, looking at source code

    - by Werner
    Hi, the following code comes from the matplotlib gallery: #!/usr/bin/env python from pylab import * x = array([10, 8, 13, 9, 11, 14, 6, 4, 12, 7, 5]) y = array([8.04, 6.95, 7.58, 8.81, 8.33, 9.96, 7.24, 4.26, 10.84, 4.82, 5.68]) I am new to python, and would like to change the content of x and y from an input file. I have two short questions: I could guess what array means, but once I see it on the code, how can I know to which library it belongs and more information about it? Should I use some kind of python debug commands? How do I insert the content of my input file into x? Thanks
