I know data structures and algorithms sound scary, But they are not.

If you learn them, you can pass any interview in the world. In addition, you can build awesome high-performance apps and much more.

I have seen many people get stuck in data structures and algorithms because they get overwhelmed by the topics.

They do not know where to start; they read Wikipedia pages, articles and watch tutorials but don't understand anything.

They feel like this huge mountain of knowledge that is difficult to climb up with all these ideas floating around their head.

So, in this article, I will give you **13 reasons why you should learn data structures and algorithms**.

Not only that, I'm going to write down a complete series with visual explanations in upcoming articles.

Before moving to the reasons, I want to make sure you better understand:

**Difference between Data Structures and Algorithms**
-----------------------------------------------------

**Data Structure:**

A data structure is a way in which you organize your data.

For **example**, an array can be used to store numbers.

Data structures are one of the basic building blocks of modern computer programs.

We use them without even realizing it all the time. These are the methods of arranging information for efficient processing.

They include a variety of ways to arrange information, such as books on a shelf, folders on a desk, items on an organizational chart, etc.

To use the right data structure in the digital world, you should consider whether you want to add information, search for it, or remove it.

**Algorithm:**

An algorithm is a step-by-step procedure for solving a problem or carrying out some task.

For example, to calculate the area of a rectangle you will need to follow the steps given below:

**Step 1:**

You start by drawing an imaginary line that divides the rectangle into two parts.

**Step 2:**

Next, you take half of this imaginary line and draw a line parallel to it.

**Step 3**:

This is the new starting point of your rectangle. You repeat this step until you reach the desired area (in our case, area = height * width).

You should understand that an algorithm can be described as an **explicit procedure for solving**.

**Reason # 1:**

One of the things that I think is really cool about programming is that you can use it to solve pretty much any problem.

I'm not just talking about [web development](https://www.coderchamp.com), but literally any problem.

Do you want to write a program that will help you be more productive? There's a data structure and algorithm for that.

Want to create a program that will help you find love?

There's a data structure and algorithm for that as well. 😀

Good programmers have the ability to solve problems.

Knowing how to solve problems is a skill that can't be taught.

The only way to learn to solve problems is to practice solving problems.

The best way to practice solving problems is to learn a data structure and an algorithm.
