How to approach DSA as a beginner

Data Structures and Algorithms has to be one of the most important aspects of shaping career in tech but is also the most challenging part for beginners.

You start by learning a language and then dive in different data structures. But sometimes it becomes too much and you are overwhelmed.

Even after learning the basics and spending quite some time on the problem when you are unable to come up with a brute force solution it turns everything frustrating.

This follows the cycle of avoiding DSA. But the harsh reality is, you cannot master DSA in a few days or in a few attempts, it takes continuous efforts over a long period of time to ace it.

So here's how you should approach DSA as a beginner:

1. Build fundamentals
   First, learn the basics of any programming language of your choice and implement everything you learn (for example, in IntelliJ IDEA if you're using Java).

2. Practice
   Second, ask ChatGPT or any curated platform to give you problems categorized according to topics and difficulty(Beginner to Advanced).

3. Focus on problem solving
   Third, try attempting the questions.
   Spend some time on the question and build a brute force solution.

   Note: Do not spend a lot of time on a single question, taking DSA on your ego will not only waste your time but also make you feel stuck.

4. Optimize
   If you come up with a brute force solution, try to optimize it.
   And if you are unable to, then don't worry it is quite common and normal to fail before things start clicking.
   You can always search for the solutions and try to understand the logic behind them.

5. Recognize Patterns
   Make note of the patterns involved in questions because DSA is all about patterns. Memorizing the solutions won't help you build confidence when you don't understand the logic.

6. Reinforce
   Now practice a new problem lying on the similar logic and try to implement it again.

This way slowly and gradually you will be able to build logic, improve your thinking ability and gauge concepts.

Remember, it is difficult but avoiding it won't make it easier, the trick lies in consistency.
