We have a DataListComponent that shows a data we pull from a service. DataListComponent also has a PagerComponent as it's child. PagerComponent creates page number list based on total number of pages it gets from the DataListComponent. PagerComponent also lets the DataListComponent know when user c...

According to Wikipedia: [A] software design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. It is a description or template for how to solve ...

Viewchild offers one way interaction from parent to child. There is no feedback or output from child when ViewChild is used. We have a DataListComponent that shows some information. DataListComponent has PagerComponent as it's child. When user makes a search on DataListComponent, it gets a data fro...

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...

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...

Rabin-Karp Algorithm is a string searching algorithm created by Richard M. Karp and Michael O. Rabin that uses hashing to find any one of a set of pattern strings in a text. A substring of a string is another string that occurs in. For example, ver is a substring of stackoverflow. Not to be confuse...

Matrices are essentially two-dimensional arrays. That means that it associates (i, j) coordinates, where i is the row and j is the column, to a value. So, you could have : m3, 4 = "Hello" The easiest implementation is to make an array or arrays. In python, that would go as follows. ma...

Cryptography is the science of using mathematical constructs (codes) to make communication secure. The field of cryptography is a subset of the field of Information Security. There are many cryptographic operations possible; some best known examples are: Encryption : transforming a plaintext mes...

There are two operators for pointers: Address-of operator (&): Returns the memory address of its operand. Contents-of (Dereference) operator(*): Returns the value of the variable located at the address specified by its operator. int var = 20; int *ptr; ptr = &var; cout << var &...

Let's create a very simple view to respond a "Hello World" template in html format. To do that go to my_project/my_app/views.py (Here we are housing our view functions) and add the following view: from django.http import HttpResponse def hello_world(request): html = "&lt...
