Taking Maximum Energy From the Mystic Dungeon | Leetcode 3147 | Java Hindi Explanation

🔗 Problem Link:https://leetcode.com/problems/taking-... 💻 Solution Link: https://github.com/kernelqueen/Leetco... 🧩 Solution Approach Approach: K-Step Reverse Traversal (Postfix Sum) The array is divided into k independent sequences — each starting at a different offset i (between 0 and k) For each starting index i, we traverse from the end of the array backward in steps of k. Maintain a running sum (sum) for each sequence and track the maximum energy achievable. The intuition: from any position, you can only jump ahead by k steps — so we calculate possible energy paths backward for all starting offsets. ⏱️ Time Complexity: O(n) 💾 Space Complexity: O(1) 🧠 Concepts Used: Postfix Sum, Modular Grouping of Indices, Array Traversal Optimization #LeetCode #DynamicProgramming #Array #Java #CodingInterview #PostfixSum #KStepTraversal #Leetcode3147 #MaximumEnergy #CodingSolution 0:00 Problem Description 1:15 Problem Understanding 3:18 Example to understand the Approach 7:36 Solution Approach 6:34 Code 8:02 Time & Space Complexity
