I have implemented the sort function in my codebehind, it works fine with words but not with numbers... eg 4,693 1,494 23 when i sort this i get > 1,494 > 23 > 4,693 so this means its just checking the first number.... my code for sort is: protected void GridView1_Sorting(object sender, GridViewSortEventArgs e) { ...
Hi! I have a Groovy application. I am rendering the view list using the following statement: render (view: 'list', model:[reportingInstanceList: reportingInstanceList, reportingInstanceTotal: i, params: params]) The list.gsp is as follows: The view is rendered but the default sorting is not working. <g:sortableColumn class="tabtitle...
Hi all, I have a simple table based queue system. In its simplest form, it consist of an id, a queue name, and a status. When reading the next message from a given queue, we need to ensure FIFO (first in first out), i.e. the lowest id from the given queue with the given status. This all works fine with some thousand rows, but when we re...
I have a set of objects, and I need to produce a sorted list, but my comparison function is incomplete and leaves some room for "imagination" on the part of the sorting algorithm. Specifically, given a collection of trees like the following: A E | | B--C F | D What I have on hand is the set of nodes {A, B, C, D...
What are the use cases when a particular sorting algorithm is preferred - merge sort vs quick sort vs heap sort vs introsort, etc? Is there a recommended guide in using them based on the size, type of data strucutre, available memory and cache, and CPU performance. thanks, Sam ...
The implementation below is stable as it used <= instead of < at line marked XXX. This also makes it more efficient. Is there any reason to use < and not <= at this line? /** class for In place MergeSort **/ class MergeSortAlgorithm extends SortAlgorithm { void sort(int a[], int lo0, int hi0) throws Exception { int lo = lo0; ...
Hello! I have a table I store contacts and their phones. Contact: ContactId (int, PK), FirstName (varchar), LastName (varchar) Phone: PhoneId (int, PK), ContactId(int FK), Number (varchar), SortOrder (tinyint) I want that under each contact, the user should be able to maintain the priority of the phones, meaning that the SortOrder co...
Hi I have a 5gig text file that needs to be sorted in alphabetical order What is the best algorithm to use? constraints: Speed - As fast as possible Memory - A Pc with 1 Gig Ram running windows XP ...
I need some help with my CS homework. I need to write a sorting routine that sorts an array of length 5 using 7 comparisons in the worst case (I've proven that 7 will be needed, because of the height of the decision tree). I considered using the decision tree 'hard-coded', but that means the algorithm is really complicated and was hinte...
With everything else being equal, a BoundField column in an asp:GridView is sortable, but a TemplateField column is not. Why is that? <asp:LinqDataSource ID="someDataSource" runat="server" ContextTypeName="someDataContext" TableName="someTable" OnSelecting="someSelectingHandler" /> ...
I have a DataGridView bound to xml file. I would like to sort by first column and treat values as integers (not strings). XmlDataDocument xml = new XmlDataDocument(); xml.DataSet.ReadXml("file.xml"); dataGridView.DataSource = new BindingSource(xml.DataSet, "Item"); Sort(IComparer) doesn't work Sort(DataGridViewColumn,ListSortDirecti...
Hi.

Hello, I'm running Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win 32 When I'm asking Python >>> "u11-Phrase 099.wav" < "u11-Phrase 1000.wav" True That's fine. When I ask >>> "u11-Phrase 100.wav" < "u11-Phrase 1000.wav" True That's fine, too. But when I ask >>> "u11-Phrase 101.wav" < "u11-Phr...
Helo there, im trying to figure out how to write a function that returns a multidimensional array, based on the data below: I know how to write the function using the "category_parent" value, but im just trying to write a function that can create a multidimensional array by JUST using the left and right keys. Any help greatly appreciat...
Possible Duplicate: why is in place merge sort not stable? I wrote a simple implementation that is very similar to normal merge sort (using additional memory) but adds complexity. I don't understand why in place merge sort is not stable. The behavior is the same as merge sort. See the blow implementation: /** class for In plac...
How do I sort this array? [ {id : 1, start : 60, end : 120}, {id : 2, start : 100, end : 240}, {id : 3, start : 700, end : 720} ] UPDATE: So if my array looks like this, can I sort it based on start value? [{ 1:{start : 60, end : 120}, 2:{start : 100, end : 240}, 3:{start : 700, end : 720} }] ...
i have an array like this (after i unset some elements): $array[3] = 'apple'; $array[5] = 'pear'; $array[23] = 'banana'; which function do i use to sort them to: $array[0] = 'apple'; $array[1] = 'pear'; $array[2] = 'banana'; i tried some of the sort functions but it didnt work. ...
My objective is: Given a list of entries, and a desired ordering, rearrange the list of entries according to this ordering. The list will be very large, so space efficiency is important. Ex: List<Entry> data = ReadDataFromSomeWhere(); // data => [a, b, c]; List<int> ordering = RandomPermutation(data.Count); // ordering => [2, 1, 3]; da...
For example, I have a shop order database, and two tables in it - ORDERS and ORDERSTATUS.

I have an array in scala with the class "ArrayBuffer[Actor]", where Actor is a class that implements the "Ordered[Actor]" trait. How do I sort this array without coding it manually? I know there is an Object called Sorting, but it doesnt seem to work since ArrayBuffer doesn't implement/extend the right classes. How do I sort ArrayBuffe...
