log4jGrade:If you specify a logger with a record level of info, the logger records all information that is greater than or equal to info.That is, the logger only records log information that is greater than or equal to the logger level.Inheritance relationship : 1, if the current logger does not specify a record level, then it automatically inherits the rank of a class logger that is closest to it;For exampleLogger Name levelAA ERRORBB NoneThe BB level automatically becomes error when initializ

Title Link: http://poj.org/problem?id=3666Test instructions: The minimum cost of making a sequence increment or decrement a sequence. The cost is the formula given in the question.Solution: Dp[i][j] represents the minimum cost of the number of previous I, with Num[j] as the end.Enumeration J at the time of updateTransfer status:for (int2; i int t = inf; for (int1; j min(t,dp[i-1][j]); abs(a[i] - num[j]); } }Finally, simply traverse DP [n] [K], where k

The main idea: to give an untidy road surface, you can increase or decrease a road surface, all need the cost of |x-x ' |, the road to the correction to a monotonous or monotonous non-rising minimum cost is how much.Idea: The height span of the road is a little big ah, first discretization. After F[i][j], the road surface is guaranteed to be monotonically non-descending and the maximum height for the minimum cost of J is how much, using a prefix and optimization. Monotonous does not rise also th

A third-grade mathematics question in a Vietnamese primary school After seeing this news, I felt a little speechless. This question is not so exaggerated. It is also simple to write programs. I hope that the news reported by the media will be like a news report, I hope to report more valuable news about science and technology and the economy. Let's just talk about the code. #include From the output, we can see that there are a total of 230389 soluti

[Python Data Analysis] Grade 4 score distribution and python data analysis Distribution Recently, I got some level-4 Score data, about 500 or more. So I wondered if these Score data could meet the so-called normal distribution? Let's do what we do, so we have this article.This article introduces some usage of the xlrd module and some methods of drawing bar charts and random bar charts of Custom Data Using matplotlib, and provides some links, it can be

The reasons for the high and low price of routers Different routers distinguish the price of the main because (1) different function Although the basic functions are the same, but some router differences also built into other more practical functions, such as professional firewall functions, VPN these, so the technical requirements are higher, the price will naturally increase. (2) different performance Powerful routers are built with powerful processors and large-capacity memory, so the co
