Instead of using extra space, the solution encodes both old and new values into each element using the formula: nums[i] = nums[i] + n * (nums[nums[i]] % n), where % n ensures correct value extraction. In the second pass, nums[i] is divided by n to retrieve only the newly encoded value, achieving an in-place transformation. This approach uses mathematical encoding to meet the O(1) space constraint. ✨ Timelines✨ 00:00 - Introduction 0:19 - Motivation 0:49 - Problem Explanation 3:53 - Simple Approach 4:41 - Follow Up Qn 8:20 - Detailed with example 21:50 - Story To Code 24:19 - Coding it 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
