WordPress is one of the magnificent open source web software that you can use to create a beautiful website or blog. In the beginning days of WordPress, there were some horrible problems with the way how themes were developed and maintained. There was no good way of upgrading WordPress themes without losing all the custom styling options. There was no way to prevent copying and

pasting of the same functionality code in all themes. But now, Creating custom WordPress themes is exceptionally instinctive and relatively easy using WordPress application programming interface(API).

If you’re going to design a WordPress site, there are a few ways you can start :
  • Start with an HTML template & then add WordPress code. 
  • Start with the basic WordPress code and design around that. 
  • Start with a starter theme or framework.

A differential equation (D.E.) of the form dy/dx= f (x, y) and an initial condition (x0,y0), we would like to a find function y = f (x) that satisfies the D.E. and passes through the point (x0,y0). In some cases, one can identify the general solution to the D.E. by inspection or using methods such as separation of variables and integration. But sometimes, either we don’t have the analytic tools in our tool bag to solve the D.E. or an analytic solution is not possible.That’s when we need a numerical method for solving the D.E. One such method is Euler’s Method.

In computer science we use dynamic programming for solving complex problem. A good example for dynamic programming is longest common subsequence.   
Dynamic programming is a method for solving a complex problem by breaking it down into a collection of simpler subproblems. It is applicable to problems exhibiting the properties of overlapping subproblems and optimal substructure. Sometimes the subproblems are not independent, that is when sub-problems share subsubproblems. Dynamic programming algorithm solves every sub-problem just once and then saves its answer in a table.  

Fibonacci implementation

The Fibonacci Sequence is the series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... The next number is found by adding up the two numbers before it. The 2 is found by adding the two numbers
before it (1+1) Similarly, the 3 is found by adding the two numbers before it (1+2), And the 5 is (2+3), and so on! The first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two. It is an interesting series and we all know it very well. But how many of us use it in our practical life??? Now try to solve a problem by implementing fibonacci series..

Let's see some easy ACM problems.

Happy coding...


How to Add two big number using string:

It's easy to add two numbers in any programming language. For example, if int a = 2; int b = 3, then we just add a + b . Now if we try to add two numbers each having 100 digits like 10000000000000000000000000000000000...., what should we do ?

There is no data type to hold 100 digit in a variable. So what can we do ? The process is to take input as string. Then we can add those numbers.
For example:

How to print stars pattern ( * ) in C programming ?

We can play with * and print them in many ways, many style. Let's see some awesome pattern of stars and try to do this by computer.
At first try yourself, then go to see code.

Pattern 1:

Code for this above pattern.

Pattern 2:


Code for this above pattern.

Happy coding...

In computer science, we use a group of nodes to represent a sequence data. It's a data structure operation. Link list is a way of storing data in a sequence and use those data easily. This allow us to pick or delete data in a specific location of list.


Linked List operation

Link List:

  1. Singly Link List 
  2. Doubly Link List
  3. Circular Link List
