Make Lexicographically Smallest Array by Swapping Elements | LEETCODE 2948 | Solve In Seconds |
LeetCode 2948 — Make Lexicographically Smallest Array by Swapping Elements. You may swap two elements only if their value gap is ≤ limit, so values form limit-groups (connected components). Sort value-index pairs, group by the limit, then place each group's smallest values at its smallest original indices. Result: lexicographically smallest array in O(n log n) time, O(n) space. Asked at Amazon, Google, Atlassian, Uber, IBM, PhonePe.

Notes for US interview prep
- Metadata in American English spelling (behavior, color, optimize, favorite) — applied in title/description/tags.
- Captions: upload the accurate English .srt already recorded at /Users/shaanyadav/MyStorage/youtube/Recoding/cam.srt to YouTube (do NOT rely on auto-captions; fixes technical terms like "lexicographically").
- Schedule in EST: long-form Tue/Wed 2-4 PM EST (publish 1-2h before). IST = EST + 10h30m, so 3 PM EST = 1:30 AM IST next day — use YouTube Schedule.
- Playlists: create "Amazon LeetCode Interview", "Google LeetCode", "LeetCode Daily" and add this video.
- Long-form hashtags trimmed to 2 (#LeetCode #AmazonInterview) per 2026 data (hashtags can cut long-form views).
- AI/GEO: chapters act as citable H2 chunks; clean transcript + direct-answer description help ChatGPT/Gemini/Perplexity cite the video.
