Lexicographically Smallest Palindromic Permutation Greater Than Target | LEETCODE 3734 | Solve In Seconds
The video opens with the LeetCode 3734 problem statement and two examples, then explains frequency counting and the at-most-one-odd rule. It builds the left half with greedy choices constrained by the target prefix and backtracking, mirrors it into the final palindrome, and proves the O(26*n) time / O(26) space complexity. The flash texts "YOU WILL DO IT", "HARD MADE EASIEST" and "JUST WATCH IT" reinforce confidence.

Why this approach beats the others
- Exact long-tail keyword in title, description opening, FAQ, chapters, tags and hashtags — future "optimized" videos cannot outrank.
- Real GitHub code (4 languages) with a permanent blob link — competitors only paste screenshots.
- 21-section depth: chapters, FAQ, US SEO, scheduling, AI/GEO-ready transcript structure.
- Cinematic black thumbnail with LeetCode logo + flash texts and a real bearded face — highest CTR.
Notes for US interview prep
- Metadata in American English (behavior/color/optimize).
- Upload accurate English .srt captions (NOT auto) so YouTube + Google + AI engines index the palindrome permutation logic.
- Schedule long-form Tue/Wed 2-4 PM EST (Shorts Fri 4-7 PM EST) via YouTube Schedule.
- Build playlists: Amazon LeetCode Interview, Google LeetCode, Meta LeetCode, Microsoft LeetCode (even though no company is verified for 3734, these catch sibling searches).
- Long-form hashtags trimmed to 3 (US RPM focus).
