We have n jobs, where every job is scheduled to be done from startTime[i] to endTime[i], obtaining a profit of profit[i].
You\'re given the startTime , endTime and profit arrays, you need to output the maximum profit you can take such that there are no 2 jobs in the subset with overlapping time range.
If you choose a job that ends at time X you will be able to start another job that starts at time X.
Example 1:
Input: startTime = [1,2,3,3], endTime = [3,4,5,6], profit = [50,10,40,70]
Output: 120
Explanation: The subset chosen is the first and fourth job.
Time range [1-3]+[3-6] , we get profit of 120 = 50 + 70.
Example 2:
Input: startTime = [1,2,3,4,6], endTime = [3,5,10,6,9], profit = [20,20,100,70,60]
Output: 150
Explanation: The subset chosen is the first, fourth and fifth job.
Profit obtained 150 = 20 + 70 + 60.
Example 3:
Input: startTime = [1,1,1], endTime = [2,3,4], profit = [5,6,4]
Output: 6
Constraints:
1 <= startTime.length == endTime.length == profit.length <= 5 * 10^4
1 <= startTime[i] < endTime[i] <= 10^9
1 <= profit[i] <= 10^4
你打算利用空闲时间来做兼职工作赚些零花钱。
这里有 n 份兼职工作，每份工作预计从 startTime[i] 开始到 endTime[i] 结束，报酬为 profit[i]。
给你一份兼职工作表，包含开始时间 startTime，结束时间 endTime 和预计报酬 profit 三个数组，请你计算并返回可以获得的最大报酬。
注意，时间上出现重叠的 2 份工作不能同时进行。
如果你选择的工作在时间 X 结束，那么你可以立刻进行在时间 X 开始的下一份工作。
示例 1：
输入：startTime = [1,2,3,3], endTime = [3,4,5,6], profit = [50,10,40,70]
输出：120
解释：
我们选出第 1 份和第 4 份工作，
时间范围是 [1-3]+[3-6]，共获得报酬 120 = 50 + 70。
示例 2：
输入：startTime = [1,2,3,4,6], endTime = [3,5,10,6,9], profit = [20,20,100,70,60]
输出：150
解释：
我们选择第 1，4，5 份工作。
共获得报酬 150 = 20 + 70 + 60。
示例 3：
输入：startTime = [1,1,1], endTime = [2,3,4], profit = [5,6,4]
输出：6
提示：
1 <= startTime.length == endTime.length == profit.length <= 5 * 10^4
1 <= startTime[i] < endTime[i] <= 10^9
1 <= profit[i] <= 10^4
