How to Approach Data Structures and Algorithms

To prepare effectively for coding interviews, it's crucial to have practical experience. Here's how you can approach data structures and algorithms:

1. Use Data Structures and Algorithms in Your Own Code

The best way to learn data structures and algorithms is to use them in your own code. Even if you don't have time to code everything, try to handle the more challenging problems. This will help you gain familiarity with the intricate details and better prepare you for interviews.

2. Visualize Data Structures

Mastering the visualization of data structures is key to solving complex problems. Start by sketching them out and putting your ideas on paper. This skill is essential for understanding and solving problems, from simple queues and stacks to more complex self-balancing trees.

3. Practice Incorporating Data Structures and Algorithms in Your Codes

While you need experience using data structures to solve real-world problems, consistent practice is essential. Understand when to use a hash, when to implement a tree, and when to utilize a min-heap.

Online Courses to Enhance Your Skills

To get started, I recommend using a combination of video lectures and books. Here are some top courses for learning data structures and algorithms:

1. Logicmojo

Logicmojo offers interactive live classes, 1-to-1 doubt clearing sessions, lifetime access to video lectures, peer-to-peer learning, contests, and assignments. This makes it an excellent choice for hands-on learning and personalized guidance.

2. Educative

Educative provides interactive learning modules and detailed walkthroughs, making it easy to follow along and understand complex concepts. The platform is suitable for both beginners and advanced learners.
