7. Scratch

Okay, so Scratch might seem like it’s just for kids, but hear me out. It’s actually a pretty cool way to get your head around coding concepts without getting bogged down in syntax. Think of it as coding with LEGO bricks. You drag and drop blocks to make things happen. It’s super visual, which can be a nice change of pace if you’ve been staring at lines of code all day.

I remember when my little cousin showed me what she was doing in Scratch. I was surprised by how much you could actually do. She was making a whole game with characters and everything! It made me think about problem-solving in a different way. Scratch is a great way to visualize algorithms and animations.

It’s not going to teach you Java or Python, but it can help you understand the logic behind programming. Plus, it’s free, and there’s a huge community of people sharing their projects. You can even remix other people’s creations to learn how they work. If you’re feeling burnt out or just want a fun way to unwind while still engaging your brain, give Scratch a try. You might be surprised at what you can create. It’s a good way to learn software development.

8. Google

Google provides a range of resources that can be helpful for LeetCode preparation, though they might not be direct, structured courses. Think of it as using Google’s tools and knowledge base to supplement your LeetCode grind. I remember when I was prepping, I practically lived on Google Search trying to understand different algorithms. It’s amazing what you can find!

One thing I did was focus on problems that Google actually asks in interviews. It’s a good way to narrow your focus. I found that solving Google-tagged LeetCode problems was super helpful.

Here’s how Google can indirectly help:

• Google Search: Obvious, but invaluable. Stuck on a concept? Google it. Need to understand a specific algorithm? Google it. Find explanations, code examples, and discussions on various LeetCode problems.

• Google Developers Training: While not directly LeetCode-focused, Google offers training on various programming topics, which can strengthen your overall foundation. This is especially useful if you’re newer to programming.
• TensorFlow and AI Education: Google has a lot of material on AI. If you are interested in AI, you can learn about Data Manipulation and other topics.

9. LinkedIn

LinkedIn Learning can be a surprisingly good resource for coding courses, especially if you’re already using LinkedIn for networking and job searching. It’s not exactly LeetCode, but it can help you build skills that complement your LeetCode grind. I’ve found some pretty useful courses there, and the fact that you can directly add completed courses to your profile is a nice bonus. It’s a good way to show off what you’ve learned.

LinkedIn Learning uses a subscription model, but they often have free trials or offer courses for free for a limited time. Keep an eye out for those deals! Plus, sometimes your employer might already have a LinkedIn Learning subscription that you can use. It’s worth checking out. You can also enhance your resume and LinkedIn profile by illustrating your coding proficiency to potential employers.

Here’s what I like about LinkedIn Learning for coding:

• Integration with your profile: Makes it easy to showcase your new skills.
• Variety of courses: They cover a wide range of topics, from basic programming to more advanced concepts.
• Professional focus: The courses are often geared towards practical skills that you can use in your career.

It’s not a replacement for LeetCode’s interview-specific practice, but it’s a solid addition to your learning toolkit. Think of it as a way to build a broader foundation of knowledge.

GitHub isn’t exactly a course provider, but it’s an invaluable resource for learning to code and prepping for interviews. Think of it as a giant library filled with code, projects, and learning materials created by developers all over the world. It’s a place where you can learn by doing, collaborating, and exploring real-world projects.

GitHub is great for version control, using Git (Version Control System) and collaborating with others. You can find tons of open-source projects to contribute to, which is a fantastic way to build your skills and portfolio. Plus, many developers share their interview prep materials and solutions on GitHub, making it a goldmine for resources.

Here’s why GitHub is awesome for LeetCode prep:
