Leetcode2432. The Employee That Worked on the Longest Task
There are?n
?employees, each with a unique id from?0
?to?n - 1
.
You are given a 2D integer array?logs
?where?logs[i] = [idi, leaveTimei]
?where:
idi
?is the id of the employee that worked on the?ith
?task, andleaveTimei
?is the time at which the employee finished the?ith
?task. All the values?leaveTimei
?are?unique.
Note that the?ith
?task starts the moment right after the?(i - 1)th
?task ends, and the?0th
?task starts at time?0
.
Return?the id of the employee that worked the task with the longest time.?If there is a tie between two or more employees, return?the?smallest?id among them.

Example 1:
Input: n = 10, logs = [[0,3],[2,5],[0,9],[1,15]]Output: 1Explanation: Task 0 started at 0 and ended at 3 with 3 units of times. Task 1 started at 3 and ended at 5 with 2 units of times. Task 2 started at 5 and ended at 9 with 4 units of times. Task 3 started at 9 and ended at 15 with 6 units of times. The task with the longest time is task 3 and the employee with id 1 is the one that worked on it, so we return 1.
Example 2:
Input: n = 26, logs = [[1,1],[3,7],[2,12],[7,17]]Output: 3Explanation: Task 0 started at 0 and ended at 1 with 1 unit of times. Task 1 started at 1 and ended at 7 with 6 units of times. Task 2 started at 7 and ended at 12 with 5 units of times. Task 3 started at 12 and ended at 17 with 5 units of times. The tasks with the longest time is task 1. The employees that worked on it is 3, so we return 3.
Example 3:
Input: n = 2, logs = [[0,10],[1,20]]Output: 0Explanation: Task 0 started at 0 and ended at 10 with 10 units of times. Task 1 started at 10 and ended at 20 with 10 units of times. The tasks with the longest time are tasks 0 and 1. The employees that worked on them are 0 and 1, so we return the smallest id 0.

Constraints:
2 <= n <= 500
1 <= logs.length <= 500
logs[i].length == 2
0 <= idi <= n - 1
1 <= leaveTimei <= 500
idi != idi+1
leaveTimei
?are sorted in a strictly increasing order.
其實用優(yōu)先隊列就可以的,提前定義好排序的依據(jù),只是排序的依據(jù)是2個條件處理;
有點想不起來了,就直接數(shù)組loop出來了。
