LeetCode 2024: Strategies No One's Telling You About 🤫

💡 1. Why LeetCode? Can't I land a job without it?

Absolutely, you can secure positions in startups and smaller tech firms where practical projects might weigh more. However, for roles in leading tech giants often referred to by the acronym "FAANG" (Facebook, Apple, Amazon, Netflix, Google), proficiency in LeetCode can be a game-changer.

😎 2. Which programming language should I use for LeetCode and interviews?

Big tech companies are more interested in your problem-solving skills rather than the specific language you use. If you're starting from scratch, C++ and Python are highly recommended due to their simplicity and widespread use in solving algorithmic problems.

🆕 3. I'm new to data structures and algorithms. Where should I begin?

Understanding the basics of time complexity and fundamental data structures (like arrays, stacks, binary trees, linked lists, queues, and hashmaps) is crucial. Familiarity with Big O notation is also essential before you tackle your first LeetCode problem.

🔎 4. With thousands of problems on LeetCode, which ones should I focus on?

Begin with problems sorted by topic to build a solid understanding. Start with easy questions and gradually move to medium ones. Save the hard problems for later.

😒 5. I know the basics. What next?

Dive into curated lists like LeetCode 75, top 100 liked, or top 150 interview questions. Avoid spending too much time on questions with high dislike ratios to stay motivated.

♾️ 6. How many problems should I aim to solve?

For beginners, aiming for 300-400 problems is a good benchmark. Remember, focus on the learning process over sheer quantity.

⭐ 7. Approaching a new problem: any tips?

Take your time to understand the problem. Start with a brute-force approach and think about how you can optimize. Sketching out your thoughts on paper can also help.

⏱️ 8. When to look at the solution if I'm stuck?

Give it about 30-60 minutes, then consider looking at hints or solutions. Don’t let a single problem consume too much of your time.

🌟 9. How can I solve problems faster?

Recognizing patterns is key. Many problems share similar strategies or solutions, so learning to identify these can speed up your process.

🤯 10. Should I memorize solutions?

Memorizing solutions is not the way to go. It won't enhance your problem-solving skills, which are crucial during interviews. Interviewers often ask follow-up questions or variations of a problem.
