Subset Sum Problem Explained | DP | Memoization | GFG | Easiest Explanation | MAANG Prep
In this video, we solve the Subset Sum Problem, one of the most important Dynamic Programming problems from GeeksforGeeks, explained in a simple and intuitive way.
You’ll clearly understand:
What the Subset Sum problem is asking
How to identify it as a Dynamic Programming problem
Recursive approach and why it is inefficient
DP state, transitions, and base cases
Top-Down (Memoization) approach
Bottom-Up (Tabulation) approach
Time and Space Complexity explained simply
This problem is a foundation for many DP problems like Partition Equal Subset Sum, Knapsack, and Target Sum, making it a must-watch for interview preparation.
Perfect for:
Beginners learning Dynamic Programming
Students preparing for coding interviews
GFG and LeetCode problem solvers
Understanding DP decision-based problems
