Minimum Moves to Clean the Classroom | LEETCODE 3568 | Solve In Seconds | Bloomberg Interview

This video walks through LeetCode 3568: Minimum Moves to Clean the Classroom, a Bloomberg interview problem. We explain the BFS + Bitmask DP approach for grid traversal with energy constraints and litter collection. The solution tracks state as (row, col, energy, mask) and uses BFS to find the minimum moves. Reset areas restore energy, obstacles block movement, and the bitmask tracks which litter cells have been collected. Full Java code walkthrough included.

Why this approach beats the others

  1. Bloomberg branding (verified asking company) — most competitors do not mention the company.
  2. "Solve In Seconds" hook — fast-paced, no fluff, no classroom-style rambling.
  3. BFS + Bitmask DP explained with visual state transitions — not just code dumps.
  4. Energy management + R cell strategy clearly explained — the trickiest part most videos skip.
  5. Professional thumbnail with stored photo, LeetCode logo, Bloomberg logo, and "INTERVIEW APPROACH" text.
