There is a computer that can run an unlimited number of tasks at the same time. You are given a 2D integer array tasks where tasks[i] = [starti, endi, durationi] indicates that the ith task should run for a total of durationi seconds (not necessarily continuous) within the inclusive time range [starti, endi].
You may turn on the computer only when it needs to run a task. You can also turn it off if it is idle.
\n\nReturn the minimum time during which the computer should be turned on to complete all tasks.
\n\n\n
Example 1:
\n\n\nInput: tasks = [[2,3,1],[4,5,1],[1,5,2]]\nOutput: 2\nExplanation: \n- The first task can be run in the inclusive time range [2, 2].\n- The second task can be run in the inclusive time range [5, 5].\n- The third task can be run in the two inclusive time ranges [2, 2] and [5, 5].\nThe computer will be on for a total of 2 seconds.\n\n\n
Example 2:
\n\n\nInput: tasks = [[1,3,2],[2,5,3],[5,6,2]]\nOutput: 4\nExplanation: \n- The first task can be run in the inclusive time range [2, 3].\n- The second task can be run in the inclusive time ranges [2, 3] and [5, 5].\n- The third task can be run in the two inclusive time range [5, 6].\nThe computer will be on for a total of 4 seconds.\n\n\n
\n
Constraints:
\n\n1 <= tasks.length <= 2000tasks[i].length == 31 <= starti, endi <= 20001 <= durationi <= endi - starti + 1 你有一台电脑，它可以 同时 运行无数个任务。给你一个二维整数数组 tasks ，其中 tasks[i] = [starti, endi, durationi] 表示第 i 个任务需要在 闭区间 时间段 [starti, endi] 内运行 durationi 个整数时间点（但不需要连续）。
当电脑需要运行任务时，你可以打开电脑，如果空闲时，你可以将电脑关闭。
\n\n请你返回完成所有任务的情况下，电脑最少需要运行多少秒。
\n\n\n\n
示例 1：
\n\n输入：tasks = [[2,3,1],[4,5,1],[1,5,2]]\n输出：2\n解释：\n- 第一个任务在闭区间 [2, 2] 运行。\n- 第二个任务在闭区间 [5, 5] 运行。\n- 第三个任务在闭区间 [2, 2] 和 [5, 5] 运行。\n电脑总共运行 2 个整数时间点。\n\n\n
示例 2：
\n\n输入：tasks = [[1,3,2],[2,5,3],[5,6,2]]\n输出：4\n解释：\n- 第一个任务在闭区间 [2, 3] 运行\n- 第二个任务在闭区间 [2, 3] 和 [5, 5] 运行。\n- 第三个任务在闭区间 [5, 6] 运行。\n电脑总共运行 4 个整数时间点。\n\n\n
