真正的水题,可惜无法当场机智一下. 这样的,在一个圈圈上给你n个黑点,现在要你移动每一个黑点使得所有的点都是等间距的,每个点中最远需要一定的那个点最小可以是多少? 其实是这样来考虑的,我们可以随便设置一系列参考点,不妨直接假设为(0,n/m,2*n/m,……),这样我们直接记录所有的点依次移动到这些对应位置所需要的最大的步奏和最小的步奏,这样我们就得到了到这一系列的位置的最大和最小值.这样我们需要的最终目标位置就是在最大值和最小值的中点处. 这里理解一下吧,就是答案了..  智商拙计.... #…
一个队列如果只生产不消费肯定不行的,那么如何及时消费Ring Buffer的数据呢?简单的方案就是当Ring Buffer"写满"的时候一次性将数据"消费"掉.注意这里的"写满"仅仅是指写入位置 index达到了数组最大索引位置,而"消费"也不同于常见的堆栈,队列等数据结构,只是读取缓冲区的数据而不会移除它.一点公益系统 一点公益系统模式 一点公益平台 一点公益APP系统 一点公益商业模式定制找陈牧150-1315-1740(…
OpenCASCADE Ring Type Spring Modeling eryar@163.com Abstract. The general method to directly create an edge is to give a 3D curve as the support(geometric domain) of the edge. The curve maybe defined as a 2D curve in the parametric space of a surface…
最近常收到SOD框架的朋友报告的SOD的SQL日志功能报错:文件句柄丢失.经过分析得知,这些朋友使用SOD框架开发了访问量比较大的系统,由于忘记关闭SQL日志功能所以出现了很高频率的日志写入操作,从而偶然引起错误.后来我建议只记录出错的或者执行时间较长的SQL信息,暂时解决了此问题.但是作为一个热心造轮子的人,一定要看看能不能造一个更好的轮子出来. 前面说的错误原因已经很直白了,就是频繁的日志写入导致的,那么解决方案就是将多次写入操作合并成一次写入操作,并且采用异步写入方式.要保存多次操作的内容…
AlwaysOn Ring Buffers 一些AlwaysOn的诊断信息可以从SQL Server ring buffers.或者从sys.dm_os_ring_buffers.ring buffer在SQL Server启动的时候被创建,SQL Server系统为内部诊断记录警告. 通过以下查询获取所有事件记录 SELECT * FROM sys.dm_os_ring_buffers WHERE ring_buffer_type LIKE '%HADR%' 为了让数据更加可控,可以通过日期,…

Ring buffers and queues The data structure is extremely simple: a bounded FIFO. One step up from plain arrays, but still, it’s very basic stuff. And if you’re doing system programming, particularly anything involving IO or directly talking to hardwar…

ring.Ring 是一个环链. 其Link操作规则是: r.Link(s) => t = r.Next r.Next.Prev = s.Prev s.Prev.Next = r.Next r.Next = s s.Prev = r return t ------------------------------------- 此规则造成: 1. 如果r,s是不同的环链, 则结果是创建一条大环链. 2. 如果r,s是相同的环链, 则删除r,s之间的点形成另一条环链. 并做为结果返回. 如果r,s是…

循环队列:队列有着先入先出的特性.但是对于队列如果删除队头以后剩下的空间将不会被释放,又由于队列只能由队尾插入这就导致被删除部分的空间被浪费.解决这个问题就是循环队列.循环队列顾名思义就是将队列串起来形成一个类似与环的结构.如图所示.对照着图很容易理解:对于原来队列里的操作自然有不同的地方:1.判断满:循环队列的满不再是rear=front 而是改成(rear-front+maxn)%maxn.2.入队操作: data[rear] = x; rear = (rear+1)%maxn; 总体思想就…
