LeetCode 190 | Reverse Bits | Bit Manipulation | Fast & Interview-Proven Solution | Pen & Paper

In this video we solve LeetCode 190 — Reverse Bits step-by-step with:
• a clear bit-by-bit implementation (easy to code in interviews),
• a fast bit-hack / swap-mask method (optimal constant-time operations), and
• a lookup-table optimization for repeated calls.
This lesson is tailored for manned preparation and general interview prep — ideal for coding rounds at big tech companies.

Asked in interviews by: Amazon and other major companies (reported in prep resources and interview logs).

• Explanations & optimized patterns (bit masks, divide-and-conquer, lookup table).

• Company-question logs / interview trackers that list this problem (Airbnb, Microsoft, Grofers, Texas Instruments in some trackers).

Why watch this (short) video?
• You’ll learn 3 distinct patterns you can pull out in interviews (bit-by-bit, bit-hacks, memoized lookup).
• I explain which approach the interviewer expects vs which impresses (practical vs micro-optimized).
• Perfect for quick last-minute review for onsite/phone rounds.
