Using the range [day - forget + 1, day - delay], we check all previous valid sharers. Memoization avoids recomputation, giving O(n * (forget - delay)) time and O(n) space. Approach-2: Bottom-Up DP We iteratively compute t[day], the number of new learners each day. A sliding window tracks sharers: add when someone becomes eligible, subtract when they forget. This reduces complexity to O(n) time and O(n) space. Approach-2: Bottom-Up Optimized Instead of recomputing the sum of sharers for each day, we maintain a running count that adds the new sharer entering the window (day - delay) and removes the one leaving it (day - forget). This reduces the complexity from O(n·(forget−delay)) to O(n) while still using O(n) space. ✨ Timelines✨ 00:00 Introduction 00:12 Motivation 00:23 Problem Explanation 04:53 Thought Process + Why Recursion 25:31 Coding Recursion Memoization 29:40 Understanding Bottom Up 35:33 Coding Bottom Up 37:18 Optimized Bottom Up 43:38 Coding Optimal Bottom Up #MIK #mik #Mik #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #hindiexplanation #hindiexplained #easyexplaination #interview#interviewtips #interviewpreparation #interview_ds_algo #hinglish #github #design #data #google #video #instagram #facebook #leetcode #computerscience #leetcodesolutions #leetcodequestionandanswers #code #learning #dsalgo #dsa #coding #programming #100daysofcode #developers #techjobs #datastructures #algorithms #webdevelopment #softwareengineering #computerscience #pythoncoding #codinglife #coderlife #javascript #datascience #leetcode #leetcodesolutions #leetcodedailychallenge #codinginterview #interviewprep #technicalinterview #interviewtips #interviewquestions #codingchallenges #interviewready #dsa #hindi #india #hindicoding #hindiprogramming #hindiexplanation #hindidevelopers #hinditech #hindilearning #helpajobseeker #jobseekers #jobsearchtips #careergoals #careerdevelopment #jobhunt #jobinterview #github #designthinking #learningtogether #growthmindset #digitalcontent #techcontent #socialmediagrowth #contentcreation #instagramreels #videomarketing #codestorywithmik #codestorywithmick #codestorywithmikc #codestorywitmik #codestorywthmik #codstorywithmik #codestorywihmik #codestorywithmiik #codeistorywithmik #codestorywithmk #codestorywitmick #codestorymik #codestorwithmik
