The find and erase operations are performed in each iteration, leading to quadratic time complexity due to repeated string modifications. Approach-2: Using Stack Time Complexity (T.C): O(n) Space Complexity (S.C): O(n) Description: This approach uses a stack to track characters. As each character is processed, it checks for the patterns "AB" or "CD". If found, it removes the matching pairs from the stack; otherwise, it adds the character to the stack. The final stack size gives the minimum length of the modified string. Approach-3: Two Pointers Time Complexity (T.C): O(n) Space Complexity (S.C): O(1) Description: This approach uses two pointers, i (write) and j (read). It iterates through the string once, checking for "AB" or "CD" patterns. If a match is found, it rewinds the i pointer to remove the pattern, otherwise, it moves forward. This method achieves optimal space usage since it modifies the string in place. ✨ Timelines✨ 00:00 - Introduction #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
