Leetcode 2772. Apply Operations to Make All Array Elements Equal to Zero
Determine whether you can reduce all elements of nums to zero by repeatedly subtracting 1 from any contiguous subarray of length k. The core challenge is deciding feasibility of windowed decrements, typically solved with a left-to-right greedy that tracks cumulative range effects (difference/sliding-window) in O(n).
