Arrays 6 | Prefix Sum Problems Solving | Lecture 19 | Java and DSA Foundation Course

We understand that arrays are a vast and complex topic. That is why we have broken it down into sections and have created separate lectures for every new concept. This will help you to understand the implementations in a clear and better way.
We recommend that you practice the class and assignment questions regularly to gain the maximum out of these lectures.
Here, Manvi mam is going to cover the array-based problems like prefix sum that are frequently asked in good placement and internship interviews.
