Phone Battery Discharge Scheduling

Schedule or select phone activities under battery discharge constraints to maximize usable time or completed work. Examples Example 1: Input: t = 10 capacity = [3,4,2] recharge = [5,6,8] Output: [0,1,2] Explanation: Battery 0 runs from real-time 0 to 3 (full discharge), battery 1 from 3 to 7 (full discharge), battery 2 from 7 to 9 (full discharge). At real-time 9, battery 0 is back (recharged at 8) and runs for 1 more minute before the phone hits 10 minutes of usage — partial use, not counted. Example 2: Input: t = 10 capacity = [5] recharge = [5] Output: [0,0] Explanation: Battery 0 runs 0..5 (full discharge, ready again at 10). Phone is off from real-time 5 to 10. At real-time 10, battery 0 runs another 5 minutes (full discharge), bringing usage to 10. Example 3: Input: t = 4 capacity = [5] recharge = [10] Output: [] Explanation: Battery 0 provides 5 minutes of capacity but only 4 are used before the phone hits the runtime target — partial use, never fully discharged. Constraints 1 <= t <= 10^4 1 <= capacity.length == recharge.length <= 10^3 1 <= capacity[i] <= 10^4 0 <= recharge[i] <= 10^4
