  • Search Complexity of a Hashtable within a Hashtable?

    - by spacker_lechuck
    Say we have a hashtable of size m, and at each bucket we store a hashtable of size p. What would the worst case/average case search complexity be? I am inclined to say that since computing a hash function is still atomic, the only worst case scenario is if the value is at the end of the linked list in the hashtable of size p, so O(n)? I have no idea how to calculate the average case for this scenario and would appreciate any pointers!

  • Google Analytics API and Internal Search question

    - by Am
    I'm trying to use Google Analytics API to query internal searches that happen on my site. I'd like to be able to query the keywords and the number of times that keyword was used in internal search, based on URL of a page on the site. The idea is to find out which keywords direct the user to a particular page. Does anyone know which dimensions and metrics must use to query that information?

  • UITableView Search

    - by lkl
    Hi all, I'm using the following code for my search on my table: - (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope { [searchParent removeAllObjects]; for(NSString *a in parent) { NSComparisonResult result = [a compare:searchText options:(NSCaseInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; if(result == NSOrderedSame){ [searchParent addObject:a]; } } } It's working fine, however, only for one character. I get the following in the console: *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)' Any help is appreciated greatly! Thanks

  • How to extract Twitter username from Search API via PHP

    - by Alexia
    The Twitter Search api returns results in ATOM/XML format which look like this: <author> <name>username (Friendly Name)</name> <uri>http://twitter.com/username</uri> </author> In my PHP I can get the name field as a variable, so it would look like this: $names = "username (Friendly Name)" But I want to use PHP to extract them as seperate variables, like this: $username = "username" $friendlyName = "Friendly Name" (without parantheses) TIA!

  • C++ print out a binary search tree

    - by starcorn
    Hello, Got nothing better to do this Christmas holiday, so I decided to try out making a binary search tree. I'm stuck with the print function. How should the logic behind it work? Since the tree is already inserting it in a somewhat sorted order, and I want to print the tree from smallest values to the biggest. So I need to travel to the furthest left branch of the tree to print the first value. Right, so after that how do I remember the way back up, do I need to save the previous node? A search in wikipedia gave me an solution which they used stack. And other solutions I couldn't quite understand how they've made it, so I'm asking here instead hoping someone can enlight me. I also wonder my insert function is OK. I've seen other's solution being smaller. void treenode::insert(int i) { if(root == 0) { cout << "root" << endl; root = new node(i,root); } else { node* travel = root; node* prev; while(travel) { if(travel->value > i) { cout << "travel left" << endl; prev = travel; travel = travel->left; } else { cout << "travel right" << endl; prev = travel; travel = travel->right; } } //insert if(prev->value > i) { cout << "left" << endl; prev->left = new node(i); } else { cout << "right" << endl; prev->right = new node(i); } } } void treenode::print() { node* travel = root; while(travel) { cout << travel->value << endl; travel = travel->left; } }

  • How do you display a binary search tree?

    - by fakeit
    I'm being asked to display a binary search tree in sorted order. The nodes of the tree contain strings. I'm not exactly sure what the best way is to attack this problem. Should I be traversing the tree and displaying as I go? Should I flatten the tree into an array and then use a sorting algorithm before I display? I'm not looking for the actual code, just a guide where to go next.
