The approach starts by converting the range endpoints to strings and focusing on counting how many valid numbers are less than or equal to a given bound. For each digit in the prefix (before the suffix), we count all combinations where that digit is strictly less than the corresponding digit in the bound, multiplying by the number of valid combinations that can follow. If the digit is greater than the limit, all further digits would have exceeded the constraint, so we break early. After processing the prefix, we check if the suffix of the number is greater than or equal to the target suffix and add one more to the count if so. Finally, we compute the result by subtracting the count up to start - 1 from the count up to finish, effectively getting the number of valid integers in the range [start, finish]. ✨ Timelines✨ 00:00 - Introduction 0:23 - Motivation 0:41 - Problem Explanation 3:40 - How to find possible count 5:34 - Thought Process 12:00 - Example Dry Run 27:49 - Another Important Example 31:13 - One Edge Case 38:00 - 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
