Given a list of intervals with values, find the peak sum (i.e. I may receive compensation if you buy something. The only difference between the 0/1 Knapsack optimization problem and this one is that, after including the item, we recursively call to process all the items . Step 4: Identifying the base cases. But first, lets go what dynamic programming is. For our house robber problem, we already discussed a couple possible base cases when we were trying to figure out the recurrence relation: One of the reasons why I personally believe that DP questions might not be the best way to test engineering ability is that theyre predictable and easy to pattern match. Have you seen the system design interview somewhere? Coding interviews are getting tougher every day. I am looking to grind the equivalent problems on LC. As the name suggests, this technique uses a Min-Heap to find the smallest element and a Max-Heap to find the biggest element.
