Knapsack DP Explained from Scratch | Competitive Programming | Vikas Soni

This lecture is part of the Dynamic Programming Complete Roadmap (Basic to CF 1900) playlist. In this video, we dive into Knapsack Dynamic Programming, one of the most important and frequently asked topics in competitive programming.

Many problems on platforms like Codeforces, CodeChef, and LeetCode are based on variations of the knapsack problem. Mastering this concept will help you optimize choices under constraints and build efficient DP solutions.

What you will learn in this video:

• Introduction to Knapsack DP
• 0/1 Knapsack problem and its intuition
• Transition from recursion to memoization
• Converting memoization to tabulation
• Space optimization techniques
• Variations like subset sum and partition problems
• Identifying knapsack patterns in contests
• Solving practice problems for strong understanding

This lecture focuses on building a strong intuition for decision-making problems where you need to maximize or minimize values under given constraints.

Playlist Goal:

By the end of this playlist, you will be able to confidently solve Dynamic Programming problems up to Codeforces 1900 rating and significantly improve your competitive programming skills.
