Most people reverse the whole string or build extra arrays. The clean interview-ready solution is simpler: use two pointers and swap only the vowels as you move inward. One pass, O(n), minimal code. In this video, I solve LeetCode 345: Reverse Vowels of a String in C++ with a clear, modern approach: Use two pointers (l, r) from both ends Skip non-vowels efficiently Swap vowels when both pointers land on vowels Continue until pointers cross Why this works (quick intuition): We don’t care about consonants at all. Two pointers let us find the next vowel from the left and the next vowel from the right, then swap them — exactly what “reverse vowels” means. What you’ll learn (and what interviewers want to see): How to implement the two-pointer pattern cleanly How to check vowels fast (including uppercase) How to avoid extra memory / unnecessary loops Edge cases: no vowels, single vowel, mixed case, already “reversed” vowels Problem Link: https://leetcode.com/problems/reverse-vowels-of-a-string/ Watch the full LeetCode 75 Series (C++ Explained): https://lanacademy-school.thinkific.com/courses/leetcode75 This video is perfect for: Developers preparing for coding interviews (FAANG, startups, etc.) Students who want to understand algorithms deeply, not just memorize solutions Anyone improving their DSA (Data Structures & Algorithms) skills Follow LAN Academy: Website: https://lanacademy-school.thinkific.com YouTube: @lanacademy9521 Twitter: https://x.com/SolutionsLan #LeetCode #C++ #DSA #CodingInterview #Algorithms #LANAcademy #LeetCode75 #InterviewPrep #StringManipulation #TwoPointers #LeetCode345 @reper #foryou #viral #reper #urmaritori #for
