Leetcode 2398. Maximum Number of Robots Within Budget
Find the maximum length of a contiguous subarray (consecutive robots) such that max(chargeTimes in the window) + window_length * sum(runningCosts in the window) <= budget. The core challenge is maintaining the window's running sum and its maximum efficiently (e.g., with a monotonic deque and two-pointers) to test feasibility while expanding/shrinking the window.
