Although Gnu/linux is not omnipotent, it does offer free, open solutions in many cases. These two days I want to do a simplified, search the online score typesetting software, found the Lilypond software based on the GPL protocol. But Lilypond is used to make staff. Fortunately, a jianpu-ly.py script written by Silas of Cambridge University was found to be able to eventually generate simplified by calling Lilypond. See here for a detailed description of it.The script supports the following simpl

Metricbeat Light-weight indicator collector
Used to collect metrics from systems and services. From CPU to memory, from Redis to Nginx,metricbeat, you can deliver a variety of system and service statistics in a light-weight way.
System-level monitoring, more concise
Deploy Metricbeat to all your Linux, Windows, and MAC hosts and connect it to Elasticsearch: you get system-level CPU usage, memory, file system, disk IO and network IO statistics, and get the same Statistics for eac

Kadane algorithm, Kadane algorithm is, if the previous sum is less than 0, recalculate sum, if sum is not less than 0, then continue to add. Then look at the divide and conquer method: There are three possibilities for any array: 1. Its maximum subarray falls on its left side; 2. Maximum Subarray falls on its right side; 3. Maximum Subarray falls in the middle of it. For the first, two cases, the use of dichotomy is easy to get, base case is if there is only one number, then return. For t

Question: There are a group of people, playing table tennis games, 22 catch to kill, every two people to play a maximum of a game.
The rules of the game are as follows:
If a defeated B,b and defeated C, and A and C did not play, then it is decided that a must be able to defeat C.
If a defeated B,b and defeated C, and C defeated A, then a, B, C Three will not be the champion.
According to this rule, there is no need to cycle a contest, perhaps to determine the championship. Your task is to face
