Q & A

What makes this DSA sheet different from others available online?

This DSA sheet is unique because it categorizes problems by topics and patterns, with questions arranged based on the difficulty students face while solving them. It also includes both general DSA concepts and company-specific problems, particularly for OA (Online Assessments) rounds of companies like Google, TCS, and Facebook.

Why did the creator choose to focus on LeetCode for this DSA sheet?

LeetCode was chosen because it is widely used by students, and the majority of DSA practice is done on that platform. Despite other platforms being created, students consistently prefer LeetCode, which is why it was leveraged for this sheet.

How are the questions structured in the DSA sheet?

The questions are divided into topics, each of which is further broken down into patterns. Within each pattern, questions are organized from easy to difficult based on the challenges students face rather than the difficulty level assigned by LeetCode.

Can beginners use this DSA sheet effectively?

Yes, beginners can use the sheet effectively. It includes programming fundamentals, such as C++, Java, Python, and JavaScript, along with articles and concepts designed to help those starting from scratch. There are also simple explanations for common programming topics like loops, variables, and conditionals.

What are the main features included in this DSA sheet to help students stay motivated?

The sheet includes a rewards system where students earn medals for solving problems and maintaining streaks. The current and maximum streaks are displayed, and students can track their progress over time. The goal is to keep learners motivated and engaged throughout their DSA journey.

How does the DSA sheet cater to students with specific concept struggles?

The sheet allows students to focus on particular concepts where they may be struggling, such as recursion or sliding window. It offers a wealth of problems for each concept, allowing students to focus on targeted practice.

What is the purpose of the 'Revision List' feature in this DSA sheet?

The 'Revision List' feature allows students to mark questions they find difficult or have taken hints on, ensuring that they can revisit those questions later for further practice and revision.

How does the sheet address advanced topics like Dynamic Programming?

The sheet covers both beginner and advanced topics in Dynamic Programming (DP). It includes various patterns such as Linear DP, 2D DP, and problems like Longest Increasing Subsequence (LIS) and Longest Common Subsequence (LCS), helping students gradually tackle more complex DP problems.

How can students track their progress in this DSA sheet?

Students can track their progress through the sheet's built-in features, including viewing the last seven days of activity, tracking streaks, marking questions for revision, and seeing their progress in each sheet. Additionally, there are notifications for completing sections.

What is the purpose of the 49-day contest mentioned in the video?

The 49-day contest is designed to encourage consistent problem-solving. Students must solve two problems daily from the sheet, maintain a streak, and post their progress on LinkedIn. Prizes such as headphones, mechanical keyboards, and free course access are offered to motivate participants.
