    按照时间顺序,模拟一下就行了

    There are n servers in a laboratory, each of them can perform tasks. Each server has a unique id — integer from 1 to n.

    It is known that during the day q tasks will come, the i-th of them is characterized with three integers: ti — the moment in seconds in which the task will come, ki — the number of servers needed to perform it, and di — the time needed to perform this task in seconds. All ti are distinct.

    To perform the i-th task you need ki servers which are unoccupied in the second ti. After the servers begin to perform the task, each of them will be busy over the next di seconds. Thus, they will be busy in seconds ti, ti + 1, ..., ti + di - 1. For performing the task, kiservers with the smallest ids will be chosen from all the unoccupied servers. If in the second ti there are not enough unoccupied servers, the task is ignored.

    Write the program that determines which tasks will be performed and which will be ignored.

    Input

    The first line contains two positive integers n and q (1 ≤ n ≤ 1001 ≤ q ≤ 105) — the number of servers and the number of tasks.

    Next q lines contains three integers each, the i-th line contains integers tiki and di (1 ≤ ti ≤ 1061 ≤ ki ≤ n1 ≤ di ≤ 1000) — the moment in seconds in which the i-th task will come, the number of servers needed to perform it, and the time needed to perform this task in seconds. The tasks are given in a chronological order and they will come in distinct seconds.

    Output

    Print q lines. If the i-th task will be performed by the servers, print in the i-th line the sum of servers' ids on which this task will be performed. Otherwise, print -1.

    Example
    Input
    4 3

    21 8 8
    
    Output
    6
    9
    30
    -1
    15
    36
    
    Note

    In the first example in the second 1 the first task will come, it will be performed on the servers with ids 12 and 3 (the sum of the ids equals 6) during two seconds. In the second 2 the second task will come, it will be ignored, because only the server 4 will be unoccupied at that second. In the second 3 the third task will come. By this time, servers with the ids 12 and 3 will be unoccupied again, so the third task will be done on all the servers with the ids 123 and 4 (the sum of the ids is 10).

    In the second example in the second 3 the first task will come, it will be performed on the servers with ids 1 and 2 (the sum of the ids is 3) during three seconds. In the second 5 the second task will come, it will be performed on the server 3, because the first two servers will be busy performing the first task.

    {
    	int t;
    	int k;

    }an[100005];
    int main()
    {
    	int n,task,time[105]={0};
    	scanf("%d%d",&n,&task);
    	for(int i=0;i<task;i++)
    	{
    		scanf("%d%d%d",&an[i].t,&an[i].k,&an[i].d);
    	}
    	for(int i=0;i<task;i++)
    	{
    		int num=0,j=1,ans=0,ser=n;
    		if(an[i].k>n)
    		{
    			printf("-1\n");

    			{
    				num++;
    			}
    			if(num==an[i].k)
    				break;
    			j++;
    		}

  • 问题描述 本地编译的Nacos-1.0 ...failed to req API:/nacos/v1/ns/instance after all servers([127.0.0.1:8848]) 网上查询说是因为以集群方式启动导致的,更改为单机模式启动即可(standalone)。 有三种解决方式

    问题描述

    本地源码编译Nacos-1.0 master分支,配置好mysql后,作为服务中心和配置中心启动成功
    但是网关应用启动时报错500 空指针异常。

    failed to req API:/nacos/v1/ns/instance after all servers([127.0.0.1:8848])

    网上查询说是因为以集群方式启动导致的,更改为单机模式启动即可(standalone)。
    但是源码不是很熟,配置里改貌似没起效。

    解决方式

    方法一

    临时先在nacos-console项目中的main方法里加了系统配置后,正常使用,我这里使用的是嵌入式数据库。

    @SpringBootApplication(scanBasePackages = "com.alibaba.nacos")
    @ServletComponentScan
    @EnableScheduling
    public class Nacos {
    
        public static void main(String[] args) {
            System.setProperty("nacos.standalone", "true");
            SpringApplication.run(Nacos.class, args);
        }
    }
    

    暂时不清楚在配置文件里配的nacos.standalone=true不生效具体原因,可能是放错了文件,有机会再填坑

    方法二

    (本地未编译的项目和已编译的包都有效)
    添加启动参数-Dnacos.standalone=true

    方法三

    如果下载的是已编译完成的nacos。可以直接加命令启动
    ./bin/startup.sh -m standalone

    统一回复下评论
    • 我这个是本地源码编译启动和测试的时候遇到的问题。
    • 如果是集群模式报错,建议查阅官方文档和issue,检查部署环境、配置文件、IP地址。
    • 如果IP地址有问题可以参考这篇文章:https://blog.csdn.net/zimou5581/article/details/91041239
