In this video, Ali tackles the famous "House Robber" problem from LeetCode. This is a classic introductory problem for Dynamic Programming (DP).
The instructor walks through the problem statement: you are a robber trying to maximize your loot from a row of houses, but you cannot rob two adjacent houses. We explore the optimal substructure and overlapping subproblems that make this a perfect candidate for DP.
The video explains:
The problem constraints and logic.
Defining the DP state: `dp[i]` = maximum loot from the first `i` houses.
Deriving the recurrence relation: `dp[i] = max(dp[i-1], dp[i-2] + nums[i])`.
Handling base cases (`dp[0]` and `dp[1]`).
Live implementation in C++ on LeetCode.
