9 Best YouTube Channels For Data Structures And Algorithms

Best YouTube Channels For Data Structures And Algorithms

If you’re interested in learning programming, knowing data structures and algorithms is a must.

With multinational companies creating very extensive applications to meet the needs of this information age, storing data properly has become a necessity.

This is because modern companies leverage this data to make informed decisions as well as present the right solutions to their customers.

These companies, therefore, need to be able to efficiently store data, in order to easily process it and retrieve the necessary information.

Let’s take the example of two programmers. One is a bad programmer and the other is a good programmer.

A bad programmer simply looks for a way to make his code run, while praying for as few bugs as possible.

He or she simply writes the code, clunky or not, they simply focus on the code running with little thought to the efficiency of the written code.

“It works”. That’s what a bad programmer thinks after successfully compiling their application.

A good programmer, on the other hand, looks for the most efficient way to solve the problem.

In my early years as a programmer, I kept wondering why my Java instructor was wasting our time forcing us to implement our LinkedList data structure.

Why couldn’t we simply use the LinkedList Class, already available in Java, like it was meant to, in order to make our lives easier, I thought.

It’s only later when I started advancing in software development, that I got to understand the importance of having a better understanding of data structures.

What is data structures and algorithms​

A data structure is a memory location that can be used to store data to subsequently perform efficient operations on them and an algorithm is an outlined systematic approach or procedure to accomplish a specific action.

Data structure is the fundamental building block of computer science and necessary for the design and development of efficient software.

To put it simply, data structures enable users to store information more efficiently for easy retrieval and an algorithm is essentially a formula that solves a particular problem.

Imagine having a bunch of files scattered around your office. There may be room for all the scattered files but the challenge arises when you need a specific file from the stack of scattered files.

Not only that, imagine needing to look for files containing some specific information. Looking through every scattered file would be a herculean task.

For this reason, we all use some form of organizational system in our offices, homes, and our daily lives.

Maybe a cabinet, folder, or binder to store specific files. In real life, we can use these devices and use the dictionary method to help identify each file.

Let’s say we’re looking for a file by the name “Priority”. We can shorten the time necessary to find this file by simply grouping our files by the first letter.

Then we can arrange files starting with the same letter, by the letter which follows, and continue to do so with subsequent letters.

This process is easier and cuts down the time necessary to find any information. It’s been used in our dictionaries and offices for years because of its efficiency.

Now, imagine how many videos are uploaded to YouTube daily, or even how much information companies like Facebook collect and store daily.

Without an organizational system, this becomes impossible. This is why most companies in recent years place a huge emphasis on data structures.

Learning Java, C#, JavaScript, PHP, Ruby, Python, or any other programming language is great but an understanding of data structures will help make it easier to understand how the programming language works.

Why learn data structures and algorithms​

Although most programming languages continue to increase the libraries programmers can use in their development, your specific situation may require some more efficiency.

Granted you can always import multiple classes and manipulate some methods to accomplish your desired task, but this doesn’t make you a good programmer.

A clunky code simply leads to problems in the future as well as increased run-time. Most large companies always strive for speed as it’s a huge competitive advantage in multiple industries.

Understanding data structures will enable you to identify the best approach to storing a company’s complex data and even implement the most efficient system from scratch.

Modern software development or SaaS companies, place a huge emphasis on potential employees’ level of understanding of data structures.

Sometimes even more than the programming languages. To stay competitive in the corporate sector, you need to be equipped with a full understanding and implementation of data structures.

Creating nodes and looping through constants may seem complex especially if you’re new to programming, but with the right materials and constant practice, this knowledge will become one of your greatest assets as a programmer.

As a programmer, if you want companies to throw the big bucks at you, then mastering data structures and algorithms is the key.

Why learn data structures on YouTube​

With platforms like Udemy available online, you might wonder why you need to learn on YouTube.

Because YouTube is the number one video streaming platform worldwide, it’s the go-to for most video content consumers.

With the application already installed on most smartphones, accessing video content only takes a tap of a button.

Additionally, some content can easily be downloaded inside the YouTube application, for offline access.

The best part is that YouTube content is completely free for all users everywhere. This doesn’t mean that paid content is inferior in any way.

Paid content from my point of view comes with some perks especially since software development courses on platforms like Udemy include quizzes and other resources that enable formative assessment.

Some online course platforms, including Udemy, also include free courses for learners.

From my point of view, free courses are not inferior especially if you find the right course for your specific field or need.

This article outlines some of the best YouTube channels for data structures and algorithms. Bear in mind that most of these I’ve tried in the past and are recommended because I found them very useful.

I’m recommending them based on my own experience with some of them, and others based on my research.
