The partition of an integer is a way of writing it as a sum of positive integers. For example, the partitions of the number 5 are: 5 4 + 1 3 + 2 2 + 2 + 1 2 + 1 + 1 + 1 1 + 1 + 1 + 1 + 1 Notice that changing the order of the summands will not create a different partition. The partition f...

public class IntegerPartition { public static int[,] Result = new int[100,100]; private static int Partition(int targetNumber, int largestNumber) { for (int i = 1; i <= targetNumber; i++) { for (int j = 1; j <= largestNumber; j++) ...

Sometimes we need cross domain request for our API's in laravel. We need to add appropriate headers to complete the cross domain request successfully. So we need to make sure that whatever headers we are adding should be accurate otherwise our API's become vulnerable. In order to add headers we nee...

This is an example of using until/retries/delay to implement an alive check for a webapp that is starting up. It assumes that there will be some period of time (up to 3 minutes) where the webapp is refusing socket connections. After that, it checks the /alive page for the word "OK". It als...

For small functions that get called often, the overhead associated with the function call can be a significant fraction of the total execution time of that function. One way of improving performance, then, is to eliminate the overhead. In this example we use four functions (plus main()) in three so...

If you enable prettyUrl in your yii2-app, your redirect_uri will be: http://<base_url>/web/site/auth And disable pretty url: http://<base_url>/web/index.php?r=site%2Fauth Example:

/** * @param $client ClientInterface */ public function onAuthSuccess($client) { //Get user info /** @var array $attributes */ $attributes = $client->getUserAttributes(); $email = ArrayHelper::getValue($attributes, 'email'); //email info $id = ArrayHelper::getValue(...

inline int add(int x, int y) { return x + y; }

// header (.hpp) struct A { void i_am_inlined() { } }; struct B { void i_am_NOT_inlined(); }; // source (.cpp) void B::i_am_NOT_inlined() { }

inline int add(int x, int y) { return x + y; } int main() { int a = 1, b = 2; int c = add(a, b); } In the above code, when add is inlined, the resulting code would become something like this int main() { int a = 1, b = 2; int c = a + b; } The inline function ...

A* (A star) is a search algorithm that is used for finding path from one node to another. So it can be compared with Breadth First Search, or Dijkstra’s algorithm, or Depth First Search, or Best First Search. A* algorithm is widely used in graph search for being better in efficiency and accuracy, wh...

Ember-cli first requires Node and NPM to be installed on the system. Either follow the installation instructions on nodejs.org, or use a preferred package manager (such as Homebrew on OSX.) It's recommended to install latest version of each. Once its done, run the following commands to ensure insta...
