intro

Let's start with appreciating this tool I am using to edit this article (Google Chrome), a program also known as computer program.
A computer program is a collection of instructions to perform a specific task. For this, a computer program may need to store data, retrieve data, and perform computations on the data.
A data structure is a named location that can be used to store and organize data. And, an algorithm is a collection of steps to solve a particular problem.

What is data, you may ask?🤦‍♀️

so data is the collection of different numbers, symbols, and alphabets to represent information. Note that this information is unordered, hence might not have meaning.

is data structure really important?

Absolutely, the choice of a good data structure makes it possible to perform a variety of critical operations effectively. An efficient data structure also uses minimum memory space and execution time to process the structure.Learning data structures and algorithms allow us to write efficient and optimized computer programs.

Nice 😄 tell me more

Now that you have a glimpse, we have 2 types of data structure, namely:

Linear data structures-think of them as data structures where elements are arranged in a single dimension i.e. lists/arrays, stack, queue etc
Non-Linear Data Structure. - Opposite of linear, elements are arranged in many dimension i.e. one-many relationship, many-many relationship or many-one relationship. Examples of these data structures are: tree, graph, table, etc.

Sounds interesting, can you give some examples 🤔

We know how to classify data structures, so far so good. Here is a list of most used data structures:

Array/lists
Linked-lists
Dictionaries
Stacks
Queues
Binary trees
Heaps

summary and next steps

Today we have learned what is data, data structure and a computer program. What are different types of data structures and their examples. Next article we will take a look at most used data structures.

...My Holy Grail in HNGi8 internship.🎯

HNGi8 is back like it never left.

I couldn't help myself to wait for this virtual coding internship. I have been fascinated by the intense coding atmosphere, the adrenaline spikes and coffee nights behind the screen.For code wannabes you know this feeling.
Intro to HNG
HNG Internship is a long running, large scale virtual internship for people learning to code and design. It focuses on the post-training phase, and creates a virtual work environment for participants.It's easier when said than done, entry is free and you can enroll here. for more about info go through this site

My objective during this internship

As I move from one stage to another am looking forward to :

identify new ways to ship quality code
add on my existing knowledge on software development most importantly on backend part
Test my ability to meet deadline and enforce on time management skill
form teams,create solutions and finally form life transformative networks
Lastly, I am looking forward to a really good time.

Tutorial Section

Here are some beginner friendly tutorials to get you started.
Figma tutorial here is link to Gary Simon, he is really good at figma
Git tutorial Link here is a great tutorial by programming by mosh
pythonhere is the best tutorial for a beginner who wants to get started with python
