Topological order Count

than the topological order on the graph. We can roughly introduce a two-fork tree to merge the sub-tree into the root formula, and then promote.State design: set ANS1[X] is the number of topological order of the subtree with node x as root, and ans2[x] is the number of nodes of the subtree with x as the root.State transitions:When the tree is a two-fork tree, it is easy to find Ans2[u]=ans2[v1]+ans2[v2]+1,ans1[u]=c (Ans2[v1]+ans2[v2],ans2[v1]) *ans1[v1]*ans1[v2]. When the tree is not a two-tree

Google map Reverse Address Resolution (address query)

The term "Address Resolution" usually refers to converting a human-readable address into a location on a map.Conversely, the process of converting a location on a map to a human-readable address is called "Reverse Address Resolution ". Google geocoding API supports direct uselatlngParameters for Reverse Address Resolution. For example, the following query contains the latitude/longitude value of a location in Brooklyn: http://maps.google.com/maps/api/geocode/json?latlng=40.714224,-73.961452senso

Use VC to program screenshot Screen

Screenshots are interesting. although there are many applications such as hypersnap that can be used to capture your favorite screen image, if you can add this function to your program, you can use it more effectively. ---- The following uses VC to gradually introduce the implementation process in Windows95. first, we need to determine the area of the screenshot and define it using the lprect structure. you can intercept a window or the entire screen. the following code copies the selected scree
