I am currently pursuing MBA from a prestigious Indian institute, but like I mentioned in my previous post, I love DSA/CP as I see it as simply a way to exercise my logical reasoning and mathematical skills, and I had a recent passion revival for it. So I will solve the LC POTD everyday. Will ofc try LC hard whenever I find time and also try to give as many LC weeklies as possible, but I want to see how many regular POTD streak I can maintain, which, at the minimum, I wanna maintain to get the LC T-shirt free. Anyway, I solved today's POTD with a stupid Data Structure, but here is the problem, as well as my solution for anyone to see: <a href="https://leetcode.com/problems/maximum-non-negative-product-in-a-matrix/?envType=daily-question&envId=2026-03-23;
