Description John buys a real estate in the Caribbean and is preparing to raise cows on several islands here. So he's going to fence all the islands. Each island is a polygon. He walked in one direction along a border of the island, sometimes by boat to another island. He can start the work of the fence from any one of the polygon vertices, and at any of the vertices he arrives, he can take a boat to a vertex of another island, but after finishing the fence on that island, he must return to the
the specified Ian era of Great Britain is considered the height of the British Industrial Revolution and the apex of the British Empire. it is often defined as the years from 1837 to 1901, when Queen Victoria (often referred to as the greatest and most beloved of all the British monarchs) reigned, though implements historians believe that the passage of the Reform Act 1832 marks the true inception of a new cultural era. the specified Ian era was prece
50, time will be free again, but unfortunately, he is also old, the time is not.If the life according to the age to draw a parabola, the 40-year-old or so a person can reach the apex of life, the probability of further breakthroughs will be smaller. Judging from the historical figures, bloomer is not without, but really very few.Careful observation will find that the recruitment revelation often indicates that the age must be under 35 years old or un

XMPP and xmpp protocolsXMPP-instant messaging technology Overview
(IM -- Instant Messaging) supports real-time online conversations. If you want to send a message, you need to open a small window so that users and their friends can enter the information and both parties can see that there are many IM systems in the conversation content, for example, AOL, Yahoo IM, MSN, and QQ, the biggest difference lies in the implementation of their respective communication protocols, therefore, the core of in
the pain by making simple annotations. After installing Docblockr, all you need to do is start a line of code with/* or/**, and the rest will be handed to it. If you start with/** on the function, it will generate comments for you based on the JSDoc format. There are things that you have never used before, but once you've used them, you'll wonder how you've survived, and Docblockr is one of those examples.Docblockr supports many other languages, including: Coffeescript,typescript, PHP, ActionSc

Cells located at the edge and apex of the entire grid may have fewer than 8 cells around it. That is, there are no more cells beyond the boundaries of the grid.
The changes in the life and death of each cell will not affect the cells around the current step, but will only show up in the next stage.

The scores of several programming languages in the top of the rankings have long been declining: Java and C have been relatively low in the Tiobe list. And almost all the other top ten languages are falling every year.So which language captures this opportunity? This happens in the leaderboard about 40 bits.The rankings of some new languages are rising, especially crystal (32), Kotlin (41), Clojure (42), Hack (43) and Julia (46). Crystal's performance was particularly good, jumping from 60th pla

Karate ClubThis is a network of social relationships with 34 vertices and 78 edges. The edge of this network represents a mutual understanding among members of a karate club in a university.The NCAA Schedule NetworkThis network consists of 115 vertices and 613 edges. The apex represents a college football team, which represents a match between the football teams during the 2000 season. Both networks are standard test sets for graph clustering algorit

When the rotation is greater than 90 o'clock, the problem domain can be converted to a sharp angle, and then calculated.As
