Idea: the polygon is divided into a trapezoid, and the area of the trapezoid is D1 + D2 at the bottom of the upper layer multiplied by the upper height/2. If the two trapezoid areas are accumulated, they can be equivalent to accumulating at the bottom of the upper and lower layers, so w

All the "Rain points" can be finally divided into a trapezoid (a triangle is one of the bottom is 0), and then the lazy mark is set to the upper bottom and lower bottom of the trapezoid. The number is large. Of course, discretization is required. Pay attention to the relationship between the processing points and the line segments between points, and note that the labels may change during the update process when there are downward update labels. #include HDU

A number X matches a wild number W if they have the same length, and every non-question mark character I N X is equal to the character in the same position in W (it means so can replace a question mark W ith any digit). For example, 365198 matches the wild number 36?1?8, but 360199, 361028, or 36128 does not. Writ

How are these longitude determined? The earth is constantly spinning around its axis (the earth's axis is an imaginary line through both the north and the South Poles and the center of the Earth), and the Earth's waist draws a large circle perpendicular to its axis, so that every point on the circle is equal to the north and South poles, and this circle is called "the equator". At the north and south sides of the equator, many circles parallel to the equator are drawn, that is, "weft rings"; the

what is geocoding. The Geocoding API is an HTTP form of map service interface for programmers to invoke. The main service for those non-web program calls. For example, C #, C + +, Java, and other development languages can send HTTP requests and receive returned data. Users only need to be in the requested URL string splicing good keywords or latitude and longitude information, you can get the corresponding Baidu
