Don’t Skip This: Prefix Sum & Merge Intervals Explained for LeetCode Interviews

Day 8 of the DSA Marathon. This session focuses on a powerful mix of interview patterns that frequently appear in LeetCode and MAANG / FAANG coding interviews. 👉 Prefix Sum 👉 Hashing 👉 Merge Intervals 👉 Sweep Line Algorithm 👉 Linked List We’ll solve LeetCode interview-style problems and understand how interval-based problems and linked list logic are handled in real interview scenarios. ━━━━━━━━━━━━━━━━━━━━ 📌 TOPICS & PROBLEMS COVERED ━━━━━━━━━━━━━━━━━━━━ Prefix Sum: • Subarray Sum Equals K • Range Sum Query • Product of Array Except Self Hashing: • Two Sum • Group Anagrams • Contains Duplicate Merge Intervals / Sweep Line: • Merge Intervals • Insert Interval • Meeting Rooms • Meeting Rooms II • Minimum Number of Arrows to Burst Balloons Linked List: • Linked List Cycle • Linked List Cycle II • Middle of the Linked List #DSA #LeetCode #DSALive #LeetCodeLive #DSAMarathon #PrefixSum #HashingDSA #MergeIntervals #SweepLineAlgorithm #LinkedListDSA #CodingInterview #InterviewPreparation #MAANG #FAANG #StudyWithMe #LiveCoding #Algorithms #DataStructures • Remove Nth Node From End of List ━━━━━━━━━━━━━━━━━━━━ 🎯 SESSION GOAL ━━━━━━━━━━━━━━━━━━━━ Learn how Prefix Sum, Hashing, and interval-based problems (Sweep Line & Merge Intervals) combine with Linked List logic in real coding interviews. ━━━━━━━━━━━━━━━━━━━━ 👥 WHO THIS LIVE IS FOR ━━━━━━━━━━━━━━━━━━━━ • MAANG / FAANG aspirants • Serious LeetCode grinders • DSA interview preparation • Long focused “study with me” coding sessions ⏱ Format: Live coding + explanation 🚀 Goal: Strong DSA intuition, not memorized solutions Start from Day 1–7 to follow the full DSA marathon journey. More problems may be added during the live session based on flow.
