Minimum Operations to Equalize Binary String | Brute Force | Optimal | Intuition | Leetcode 3666

Whatsapp Community Link : https://www.whatsapp.com/channel/0029... This is the 86th Video of our Playlist "Graphs : Popular Interview Problems" by codestorywithMIK Today we will be solving a very good problem based on Graph + BFS - Minimum Operations to Equalize Binary String | Brute Force | Optimal | Detailed Intuition | Leetcode 3666 | codestorywithMIK You will also see that since we are calling Dijkstra's everytime, we can memoize its result as well because we can get the same substring start and end again and again in different subproblems. I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY. We will do live coding after explanation and see if we are able to pass all the test cases. Also, please note that my Github solution link below contains both C++ as well as JAVA code.

This works but repeatedly scans many values and revisits overlapping ranges. Approach-2 : The optimized approach observes that from a state z, all reachable newZ lie inside one continuous range and share the same parity. Instead of checking every candidate, we jump directly to valid unseen states using set + lower_bound, avoiding repeated work. So the improvement comes from exploring ranges of states efficiently instead of one-by-one transitions. ✨ Timelines✨ 00:00 Introduction 00:09 Motivation 00:24 Problem Explanation 02:34 Thought Process - Why Graph BFS ? 07:36 Brute Force 29:07 Story To Code 36:49 Coding Brute Force 41:05 Optimal Intuition 01:04:20 Time Complexity 01:06:43 Coding Optimal #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 #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
