问题 This is a common C/C++ implementation of the Interpolation Search algorithm found around the Internet. However, when used with a sorted array of some 100000 integers, the mid-variable starts generating negative array-indexes, causing a Segmentation Fault. What could the problem be? #include <stdlib.h> #include <stdio.h> #include <time.h> int interpolationSearch(int sortedArray[], int toFind, int len) { // Returns index of toFind in sortedArray, or -1 if not found int low = 0; int high = len -

问题 I need to write a method that takes 2d array 'int [][] m' and a value 'val' and check if val is in the array in the complexity of O(n) while n defined as the number of rows and m must be squared The array that can use as a parameter for my method must return true for this method: (if it returns true so the array is as requested) public static boolean test(int[][] m) { int n = m.length; for (int r = 0; r < (n - 1); r++) for (int c = 0; c < n; c++) for (int i = 0; i < n; i++) if (m[r][c] > m[r

问题 I have a fairly simple need to do a conditional update in Solr, which is easily accomplished in MySQL. For example, I have 100 documents with a unique field called <id> I am POSTing 10 documents, some of which may be duplicate <id> s, in which case Solr would update the existing records with the same <id> s I have a field called <dateCreated> and I would like to only update a <doc> if the new <dateCreated> is greated than the old <dateCreated> (this applies to duplicate <id> s only, of course

问题 I am having a list of keywords and would like to know the number of results for google search for each of those(for my research project). I am using the below code for the same. def showsome(searchfor): hits = -1 try: query = urllib.urlencode({'q': searchfor}) url = 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&%s' % query search_response = urllib.urlopen(url) search_results = search_response.read() results = json.loads(search_results) data = results['responseData'] print 'Total

问题 I'm making a WPF application that is going to have multiple skins branded in by our build system. Ideally we would like the application to list off the skins available as some builds will have one to many skins. At runtime is there a way to enumerate all the Resource Dictionaries in a specific folder? I want to avoid hard coding the XAML filenames in my codebehind as this is a changing situation. 回答1: Sort of. You can enumerate all BAML (compiled XAML) files as follows: var resourcesName =

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . An array of integers contains elements such that each element is 1 more or less than its preceding element. Now we are given a number, we need to determine the index of that number's first occurrence in the array. Need to optimize linear search. Its not homework. 回答1: My algorithm

问题 I have a multiselect with search bound to a store (with attribute string_value). Search only searches strings that start with "string to search" instead of contains "string to search" (similar to searching for '%string%' instead of 'string%'). Is there a way to do this by extending 'multiselector-search'? Below is my multiselector control bound to a form: var ms = Ext.widget('form', { xtype: 'multi-selector', width: 400, height: 300, requires: [ 'Ext.view.MultiSelector' ], layout: 'fit',
