上午在网上看到了斯考特·杨(Scott Young)的快速学习方法,感觉很受鼓舞. 现在已经读研究生了,可是发现自己自从上大学以来到现在,发现自己的学习方法有很大的问题. 我是个特别喜欢读书的人,在大学四年中,读了很多很多书籍,可是到现在,似乎都全部忘记了,书中的知识一点都没有记住,真感觉花费那么多时间,看了那么多的书,可是没有一本是自己记得牢的.我之前也一直在反思这个问题,是不是我哪里出了问题,可是人的思想习惯总是习惯于呆在惰性区域.我之前也试图做过改正,但是都没有坚持下来,今天看了斯考特·杨

一个 m x n 的Young氏矩阵是指,每一行数据都是从左到右排好序,每一列的数据也都是从上到下排好序.其中也可能存在一些INF的数据,表示不存在的元素,一个mxn的Young氏矩阵最多用来存放 r <= mn个元素. 详细见<算导>P.83 Young氏矩阵类似于堆的结构,主要实现的API包括以下: 1. void insert(int x) 功能:将一个元素x插入到矩阵中,复杂度O(m+n) 算法过程: 1) 判断矩阵是否为Full 2) 如果不为Full,插入元素到矩阵的右下角(

这题利用二叉堆维持堆性质的办法来维持Young氏矩阵的性质,题目提示中写得很清楚,不过确实容易转不过弯来. a,b两问很简单.直接看c小问: 按照Young氏矩阵的性质,最小值肯定在左上角取得,问题在于取出最小值后如何保持矩阵的性质.可以参照max_heapify中的做法,先取出最小值,然后将矩阵左上角置为最大值,这样左上角处的元素必然导致Young氏矩阵的性质违背,于是考虑该元素右边的元素和该元素下边的元素,问题是该与右边元素交换还是与下边元素交换呢?可以发现,如果与T(右)和T(下)中较小的

1    问题源起 上游系统通过公司rpc框架调用我们系统接口超时(默认超时时间为100ms)数量从50次/分突然上涨到2000次/分,在发生变化时间段里我们的系统也没有做过代码变更,但上游系统的调用确发生了变化.由于处于主要链路上,sre同学找过来询问原因,所以开始了问题排查. 2    问题初步定位 排查rpc超时的基本思路是这样的: 1)        服务端处理确实超时 2)        服务端或者客户端由于某种原因卡住 a)         磁盘清理 b)        tr线程池
