  • Find the closest palindrome number C#

    - by user294837
    Hi All, I am trying to create a console application that reads number from a file all underneath each other like so: 101 9 and then outputs into another file the closest palindrome number. So far what I have is not quite rightm i.e. I don't think I can put the class inside a method which is a bit more Java I was wandering if anyone could help at all? Thanks :) namespace PalidromeC { class Program { static public void Main(string[] args) { #region WriteAnswers try { StreamWriter sw = new StreamWriter("C://Temp/PalindromeAnswers.txt"); sw.WriteLine("Answers"); sw.Close(); }//try catch (Exception e) { Console.WriteLine("Exception: " + e.Message); }//catch #endregion #region ReadFile try { string numbers; StreamReader sr = new StreamReader("C://Temp/Palindrome.txt"); numbers = sr.ReadLine(); while (numbers != null) { Console.WriteLine(numbers); numbers = sr.ReadLine(); }//while sr.Close(); Console.ReadLine(); }//try catch (Exception e) { Console.WriteLine("Exception: " + e.Message); }//catch #endregion NearPalindromeFinder f = new NearPalindromeFinder(); int palindrome = f.findNearPalindrome(n); Console.WriteLine("Nearest Palindrome = " + palindrome); }//main public static void testFindNearestPalindrome(int n) { class NearPalindromeFinder { int findNearPalindrome(int start) { if (testPalindrome(start)) return start; else { int neg = start; int pos = start; for (int i = 0; i < start; i++) { if (testPalindrome(start-i)) { neg = start-i; break; }//if if (testPalindrome(start+i)) { pos = start+i; break; }//if }//for return (start == neg) ? pos : neg; }//else }//findNearPalindrome bool testPalindrome(int start) { if (start == 0 || start == 1) return true; String str = String.valueOf(start); String rev = new if (str.equals(rev)) return true; else return false; }//testPalindrome }//NearPalindromeFinder class }//testFindNearestPalindrome }//Program Class

  • java mapping for oracle number type

    - by aauser
    I have database with oracle number type. Could there any possible issues with using java Double when updating table with numeric column. Should i switch BigDecimal or Double is approriate type. As I fas as I know, BigDecimal is used when arbitrary precision required, when deal with prices for example. Consider simple API updatePrice(Double d) Should i persist double as is or BigDecimal.valueOf(d) is preferable ?

  • Go through a number of functions in Python

    - by Asaf
    I have an unknown number of functions in my python script (well, it is known, but not constant) that start with site_... I was wondering if there's a way to go through all of these functions in some main function that calls for them. something like: foreach function_that_has_site_ as coolfunc if coolfunc(blabla,yada) == true: return coolfunc(blabla,yada) so it would go through them all until it gets something that's true. thanks!

  • Extracting a given number of the highest values in a List

    - by James P.
    I'm seeking to display a fixed number of items on a web page according to their respective weight (represented by an Integer). The List where these items are found can be of virtually any size. The first solution that comes to mind is to do a Collections.sort() and to get the items one by one by going through the List. Is there a more elegant solution though that could be used to prepare, say, the top eight items?

  • Number of concurrent connections in Silverlight

    - by Darko Z
    Hi guys, Is there currently a way to programatically determine from within a Silverlight app the maximum number of concurrent connections that the browser will allow? I know I can do this on the server then pass it as a parameter, but I would like to know if its possible in Silverlight. This is for all versions of Silverlight including Silverlight 4 RC.

  • number of elements in a static array of a predefined size

    - by cppb
    I have an array like this: int a[100]; I am filling only the first 4 elements in this array: a[0] = 1; a[1] = 2; a[2] = 3; a[3] = 4; When I do sizeof(a)/sizeof(a[0]) it returns 100. Is there a way I can get number of elements to which I have assinged a value and thus filtering out the remaining 96 unassigned elements? thanks

  • Flex DataGrid with row number column

    - by philcruz
    I want to extend the DataGrid component so that there is a (read-only) column for the row number like you see in spreadsheets. I came across this article http://www.cflex.net/showFileDetails.cfm?ObjectID=735 but it depends on the data being unique for each row so that it can index into the array. If the data is not unique (like for an empty grid) it doesn't work. How can I implement that?
