This is the 145th Video of our Playlist "Dynamic Programming : Popular Interview Problems" by codestorywithMIK Today we will be solving a good problem based on Digit DP - Total Waviness of Numbers in Range II | Super Detailed | For Beginners | Leetcode 3753 | codestorywithMIK 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.

We track the two previous digits as state so we can detect local extrema on the fly. By memoizing states that aren't tight-bound or leading-zero affected, we efficiently reuse sub-problem results. The final answer is the total accumulated waviness summed across all valid positions and all numbers. ✨ Timelines✨ 00:00 Introduction 00:09 Motivation 01:50 Thought Process + Why Digit DP 06:33 Hints for Digit DP 26:02 Leading Zeros 46:42 Story To Code 53:03 Coding it up TLE 01:09:39 Memoization 01:07:58 Applying Memoization #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
