LeetCode 3296 | Minimum Number of Seconds to Make Mountain Height Zero | Binary Search Explained

🚀 LeetCode 3296 – Minimum Number of Seconds to Make Mountain Height Zero | Binary Search on Answer Explained (Java) In this video, we solve LeetCode Problem 3296: Minimum Number of Seconds to Make Mountain Height Zero and understand an important pattern used in coding interviews — Binary Search on Answer. This problem looks complex at first, but once you understand the thought process and pattern recognition, it becomes a powerful interview concept. We will break the problem down step-by-step and learn how to identify when Binary Search should be applied in a problem. 🧠 Problem Summary You are given: • mountainHeight → height of the mountain • workerTimes → time each worker takes to perform work Workers work simultaneously (in parallel) to reduce the mountain height. For worker i, reducing x height takes: workerTimes[i] + workerTimes[i] * 2 + workerTimes[i] * 3 + ... + workerTimes[i] * x Which means the time required increases for every next layer. Your task is to find the minimum number of seconds required to reduce the mountain height to 0. 📌 Example Input mountainHeight = 4 workerTimes = [2,1,1] Possible distribution: Worker 0 → reduce 1 height → time = 2 Worker 1 → reduce 2 height → time = 1 + 2 = 3 Worker 2 → reduce 1 height → time = 1 Since workers work simultaneously, total time = max(2,3,1) = 3 Output = 3 🔍 Key Idea This problem teaches an important interview concept: Binary Search on Answer Instead of directly calculating the minimum time, we: 1️⃣ Try a possible time 2️⃣ Check if workers can reduce the mountain height within that time 3️⃣ Adjust the search space using Binary Search This pattern appears in many coding interview problems. ⏱ Complexity Time Complexity: O(n log H) Where n = number of workers H = mountain height Space Complexity: O(1) 📢 Join Our WhatsApp Channel Get daily DSA problems, coding interview tips, and structured learning content 👉 https://whatsapp.com/channel/0029Vb80... 💻 Code & Notes Repository 🔗 All LeetCode Solutions Repository https://github.com/Gopalkushwaha1/Lee... 🔗 AlgoDiary Interview Notes + Structured Code https://github.com/Gopalkushwaha1/Alg... 🔗 Direct Problem Folder (1009) https://github.com/Gopalkushwaha1/Alg... 🔗 Direct Java Solution File https://github.com/Gopalkushwaha1/Alg... 🔗 Direct Python Solution File https://github.com/Gopalkushwaha1/Alg... 🔥 What you will learn in this video • Understanding Binary Complement • Converting decimal to binary • Flipping bits efficiently • String based solution vs Bit Manipulation solution • Writing optimized interview-friendly code • Time and Space Complexity analysis • Clean and simple Java & Python implementation 🎯 Who should watch this video? • Students preparing for coding interviews • Beginners learning Bit Manipulation • Developers practicing LeetCode easy problems • Anyone who wants to strengthen binary concepts 📌 If you found this video helpful, make sure to Like 👍, Comment 💬 and Subscribe 🔔 for more LeetCode and DSA solutions.leetcode 3296 leetcode 3296 solution minimum number of seconds to make mountain height zero binary search on answer how to identify binary search problems when to apply binary search binary search interview trick leetcode medium binary search problem leetcode 3296 java solution mountain height problem leetcode coding interview binary search pattern data structures and algorithms java dsa problems leetcode problem solving software engineer interview preparation l
