Today we will talk about the usage and differences between virtual functions and pure virtual functions in C ++. The proposal of virtual functions has been mentioned in my previous article on C ++. It is proposed to solve the ambiguity of

One day in the topic description, Z learned about the Fibonacci series and found that the series had the following rules: F [1] = F [2] = 1; F [N] = F [N-1] + F [N-2]; so Z think it is amazing, want to know whether the number of any two fiber ACCI

The first tree-like DP. This question is both dp and dfs and backpack. Dp [I] [j] indicates that the current access node number is I AND ITS subnodes are accessed for j times. Dp [I] [j] = max (dp [I] [j], dp [I] [j-r] + dp [t] [r]). T is a subnode

I recently learned about the tree division, and I will summarize it below. We can generally use the line segment tree to solve the problem when finding the maximum value of the range. However, if the k-th or k-th interval is required, the line

In fact, the solution is not complicated, that is, first finding the convex hull of all vertices, and then finding the straight line connecting each adjacent point in these convex points, at the same time, locate the endpoint of the straight line in

In the ASIHTTPRequest framework, the HTTP request-related classes include ASIHTTPRequest and ASIFormDataRequest. The most common classes are ASIHTTPRequest and ASIFormDataRequest, which is a subclass of ASIHTTPRequest, which can send data similar to
