Leetcode 3020 | Find the Maximum Number of Elements in Subset | Greedy + Edge Cases | Dry Run

🚀 Leetcode 3020 - Find the Maximum Number of Elements in Subset | Medium 📌 Problem: https://leetcode.com/problems/find-th... 💻 Source Code: https://github.com/vijaykumar0710/lee... 🚀 Subscribe to my channel:    / @vijay_kumar_710   In this video, we solve Leetcode 3020 step by step, focusing on intuition, edge cases, and why the greedy observation works. We also perform a detailed dry run so you can understand the solution instead of memorizing it. 📌 What You'll Learn: ✅ Problem Understanding ✅ Key Observation ✅ Greedy Intuition ✅ Handling All Edge Cases ✅ Detailed Dry Run ✅ Live Coding in C++ ✅ Time & Space Complexity Analysis 💡 This problem looks tricky at first because of repeated squaring and frequency handling, but once you understand the observation, the implementation becomes straightforward. 📚 Concepts Covered: • Greedy • Hash Map • Frequency Counting • Mathematical Observation • Edge Case Handling • Problem Solving 🎯 Key Takeaway: Many greedy problems are solved by identifying the correct observation rather than trying every possibility. Learning to handle edge cases is equally important for getting Accepted. ⏱ Complexity: • Time Complexity: O(n + m log log M) • Space Complexity: O(n) Where: • n = size of the array • m = number of distinct elements • M = maximum value in the array 🔥 If you found this explanation helpful, consider subscribing for more: • Leetcode Solutions • DSA Interview Preparation • Competitive Programming • Greedy Algorithms • System Design 💻 Language Used: C++ 📝 Includes: • Intuition Building • Dry Run • Live Coding • Edge Cases • Complexity Analysis #leetcode #leetcode3020 #greedy #hashmap #cpp #datastructures #algorithms #competitiveprogramming #codinginterview #dsa#hashmap #subarrays #cpp #competitiveprogramming #datastructures #algorithms #codinginterview#leetcode #leetcode3737 #hashmap #arrays #subarrays #cpp #datastructures #algorithms #competitiveprogramming #codinginterview#cpp #competitiveprogramming #datastructures #algorithms #codinginterview#dynamicprogramming #dp #memoization #recursion #cpp #competitiveprogramming #datastructures #algorithms #codinginterview#hindi #india #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge#leetcodequestions #leetcodechallenge #hindi #india #hindiexplanation #codeistory #codestor #codestory#codestory #code #hindiexplained #easyexplaination #interview#interviewtips #interviewpreparation #interview_ds_algo #hinglish #github #design #data #google #video #instagram
