## What are the Blind 75 LeetCode Questions?

As mentioned earlier, the Blind 75 list is a compilation of 75 LeetCode questions that software engineers deem essential for mastering interview problems in the tech industry. The list covers some of the most common problem categories, including arrays, strings, linked lists, trees, graphs, and dynamic programming. Each question is hand-picked based on its frequency of occurrence in past interviews and relevance to the targeted roles. The Blind 75 list is a great resource for anyone looking to improve their skills in solving leetcode questions during technical interviews. In addition, understanding the concept of linked list is crucial for solving many of the problems in the Blind 75 LeetCode List.

I’ve organized the Blind 75 LeetCode questions into a 8-week plan with the LeetCode question name, difficulty, and link provided. Each week focuses on specific topics and data structures to allow for a systematic and comprehensive preparation process. This is a curated list that will help you prepare for your coding interviews efficiently.

### Week 1:

In the first week of Blind 75, our focus will be on solving beginner-level questions that are relatively easy. This week is crucial because it establishes a strong foundation for the upcoming weeks and helps you gain a thorough understanding of fundamental concepts. Solving these initial problems will enhance your problem-solving skills and prepare you for more challenging tasks in the future.

It is important to remember that the primary objective of Week 1 is not only to solve the provided questions but also to cultivate a problem-solving mindset. Keep a positive outlook and do not feel discouraged if you encounter difficulties along the way. Every question that you answer is an opportunity for growth and will contribute to your development as a developer, thus, preparing you for your interview journey.

### Week 2:

In week 2, we will be transitioning from easy to medium-level challenges. The goal here is to gradually increase the difficulty level of the challenges so that you can gradually build your skills and confidence.
We will start by revisiting some of the easy challenges from week 1 with slight modifications to make them slightly more difficult. For example, if one of the challenges in week 1 involved printing out the first 10 even numbers, in week 2 we might modify it to print out the first 20 even numbers.

Once you have gotten comfortable with these slightly more difficult challenges, we will start introducing new challenges that are at a medium level of difficulty. These challenges will be more complex and require a bit more problem-solving skills, but they will still be achievable with the skills you have learned so far.
As always, we will provide plenty of guidance and support to help you through these challenges. Remember, the key to success is to keep practicing and never give up!

### Week 3:

Welcome back! It’s great to have you here as we continue our Blind 75 journey. Congratulations on reaching Week 3! This week, we’ll be diving into medium-level questions. Remember, even if you encounter some roadblocks along the way, don’t lose hope. Take a moment to seek out solutions and strive to understand the underlying concepts. With that said, let’s get started on this week’s challenges.

### Week 4:

In the week 4, the questions are more challenging and require more advanced knowledge from the previous weeks. These types of questions often come up in interviews, so it is important to be prepared. Additionally, this week provides an opportunity to practice using more complex data structures, including but not limited to heaps and tries, which may not be as commonly used but are still relevant for interviews.

### Week 5:

As we reach the midway point of our Blind 75 expedition, we are filled with a sense of confidence from all that we have learned. Now, we must maintain this positive energy and embrace Week 5 with open arms, prepared to face fresh obstacles and tackle further personal development.

### Week 6:

Let’s dive into what this week has in store for you. You’re entering the sixth week of your Blind 75 endeavor, and you’ve already gotten used to the daily pattern of code.  We realize that this routine can be tough, but don’t give up because the benefits you’ll reap are well worth the effort. Let’s explore what’s on the agenda for this week.

### Week 7:

Great job on finishing more than 50 questions in the last six weeks! Your commitment and perseverance are truly commendable. Nevertheless, our adventure is far from over. It’s time to step up and keep pushing forward. So, without any more delay, let’s jump back into the captivating universe of Blind 75!

### Week 8:

Greetings as we enter the last week of the Blind 75 journey! We are thrilled to present you with a series of difficult questions that will test your ability to solve complex problems. Get ready to face a challenging lineup because this week’s set of questions is tailored to push your boundaries and enhance your proficiency in DSA.
In the final week, we have put together a compilation of intricate LeetCode problems that require critical thinking and an in-depth understanding of complex algorithms. These questions are meant to test your grasp of data structures, algorithms, and their practical applications. Although the questions may appear overwhelming at first, each one you conquer is an opportunity for advancement and education.

## How to Prepare for Blind 75

Preparing for Blind 75 LeetCode questions can be challenging, especially if you aren’t comfortable with leetcode questions or practicing coding interview questions. However, there are ways to make it easier.
