HARDEST LeetCode Problem Solved LIVE (8-Pointer Problem) | Weekly 475 + Biweekly 169 Problems Solved

In this livestream, I’ll solve 3 of the hardest LeetCode problems from recent Weekly and Biweekly contests. These problems are designed to test your deep understanding of core DSA concepts, and if you’re preparing for coding rounds, interviews, or competitive programming, this is exactly what you need. I’ll walk through how to solve problems like maximizing cyclic partition score, counting subarrays with majority elements, and generating the lexicographically smallest palindromic permutation greater than a given target. Along the way, I’ll break down concepts like form 2 problem identification, cyclicity handling, max-min optimization, forming and optimizing DP expressions, multistage DP design, and more. Whether you're aiming for final-year placements, MAANG interviews, or improving your contest skills, this live session will help you level up your problem-solving mindset.
