Continuous Subarray Sum | Brute Force to Optimized | Prefix Sum + HashMap Explained |Java,C++,Python
In this video, we solve the Continuous Subarray Sum problem and understand how to move from a brute force approach to an optimized solution using Prefix Sum and HashMap. The problem asks us to check whether there exists a continuous subarray of length at least two whose sum is a multiple of k. We begin with the brute force approach, where we ...
