我想将自行sect合的多管成简单的多管。 我有数据结构(相关清单)所节省的对口和交叉点。
So here is an example. I have a connected list with the x,y coordinates of the edges and the intersection points of the polygon. According to the polygon in this picture it would be :: (1) -> (2) -> (3) ... -> (7). What I m trying to do is to get the edges of the simple polygons (triangles here). In this case :: 1,2,7 / 3,4,5 / 5,6,7.

I have a directed graph and my problem is to enumerate all the minimal (cycles that cannot be constructed as the union of other cycles) directed cycles of this graph. This is different from what the ...
Given an array of integers arr = [5, 6, 1]. When we construct a BST with this input in the same order, we will have "5" as root, "6" as the right child and "1" as left child. Now if our input is ...
I was trying to speed up a certain routine in an application, and my profiler, AQTime, identified one method in particular as a bottleneck. The method has been with us for years, and is part of a "...
