You have k
servers numbered from 0
to k-1
that are being used to handle multiple requests simultaneously. Each server has infinite computational capacity but cannot handle more than one request at a time. The requests are assigned to servers according to a specific algorithm:
ith
(0-indexed) request arrives.(i % k)th
server is available, assign the request to that server.ith
server is busy, try to assign the request to the (i+1)th
server, then the (i+2)th
server, and so on.You are given a strictly increasing array arrival
of positive integers, where arrival[i]
represents the arrival time of the ith
request, and another array load
, where load[i]
represents the load of the ith
request (the time it takes to complete). Your goal is to find the busiest server(s). A server is considered busiest if it handled the most number of requests successfully among all the servers.
Return a list containing the IDs (0-indexed) of the busiest server(s). You may return the IDs in any order.
\n\n\n
Example 1:
\n\n\nInput: k = 3, arrival = [1,2,3,4,5], load = [5,2,3,3,3] \nOutput: [1] \nExplanation: \nAll of the servers start out available.\nThe first 3 requests are handled by the first 3 servers in order.\nRequest 3 comes in. Server 0 is busy, so it's assigned to the next available server, which is 1.\nRequest 4 comes in. It cannot be handled since all servers are busy, so it is dropped.\nServers 0 and 2 handled one request each, while server 1 handled two requests. Hence server 1 is the busiest server.\n\n\n
Example 2:
\n\n\nInput: k = 3, arrival = [1,2,3,4], load = [1,2,1,2]\nOutput: [0]\nExplanation: \nThe first 3 requests are handled by first 3 servers.\nRequest 3 comes in. It is handled by server 0 since the server is available.\nServer 0 handled two requests, while servers 1 and 2 handled one request each. Hence server 0 is the busiest server.\n\n\n
Example 3:
\n\n\nInput: k = 3, arrival = [1,2,3], load = [10,12,11]\nOutput: [0,1,2]\nExplanation: Each server handles a single request, so they are all considered the busiest.\n\n\n
\n
Constraints:
\n\n1 <= k <= 105
1 <= arrival.length, load.length <= 105
arrival.length == load.length
1 <= arrival[i], load[i] <= 109
arrival
is strictly increasing.你有 k
个服务器,编号为 0
到 k-1
,它们可以同时处理多个请求组。每个服务器有无穷的计算能力但是 不能同时处理超过一个请求 。请求分配到服务器的规则如下:
i
(序号从 0 开始)个请求到达。(i % k)
个服务器空闲,那么对应服务器会处理该请求。i
个服务器在忙,那么会查看第 (i+1)
个服务器,第 (i+2)
个服务器等等。给你一个 严格递增 的正整数数组 arrival
,表示第 i
个任务的到达时间,和另一个数组 load
,其中 load[i]
表示第 i
个请求的工作量(也就是服务器完成它所需要的时间)。你的任务是找到 最繁忙的服务器 。最繁忙定义为一个服务器处理的请求数是所有服务器里最多的。
请你返回包含所有 最繁忙服务器 序号的列表,你可以以任意顺序返回这个列表。

示例 1:
\n\n\n\n\n输入:k = 3, arrival = [1,2,3,4,5], load = [5,2,3,3,3] \n输出:[1] \n解释:\n所有服务器一开始都是空闲的。\n前 3 个请求分别由前 3 台服务器依次处理。\n请求 3 进来的时候,服务器 0 被占据,所以它被安排到下一台空闲的服务器,也就是服务器 1 。\n请求 4 进来的时候,由于所有服务器都被占据,该请求被舍弃。\n服务器 0 和 2 分别都处理了一个请求,服务器 1 处理了两个请求。所以服务器 1 是最忙的服务器。\n\n\n
示例 2:
\n\n\n输入:k = 3, arrival = [1,2,3,4], load = [1,2,1,2]\n输出:[0]\n解释:\n前 3 个请求分别被前 3 个服务器处理。\n请求 3 进来,由于服务器 0 空闲,它被服务器 0 处理。\n服务器 0 处理了两个请求,服务器 1 和 2 分别处理了一个请求。所以服务器 0 是最忙的服务器。\n\n\n
示例 3:
\n\n\n输入:k = 3, arrival = [1,2,3], load = [10,12,11]\n输出:[0,1,2]\n解释:每个服务器分别处理了一个请求,所以它们都是最忙的服务器。\n\n\n
示例 4:
\n\n\n输入:k = 3, arrival = [1,2,3,4,8,9,10], load = [5,2,10,3,1,2,2]\n输出:[1]\n\n\n
示例 5:
\n\n\n输入:k = 1, arrival = [1], load = [1]\n输出:[0]\n\n\n

提示:
\n\n1 <= k <= 105
1 <= arrival.length, load.length <= 105
arrival.length == load.length
1 <= arrival[i], load[i] <= 109
