Believe that the front-end should be useful or listen to the provincial urban linkage Ajax, although I have heard before, but this is the first time in the project encountered, so tidy up their application and summary. The first is based on the absence of default values, to provide users with the choice of the provinces and Cities drop-down menu, I believe this should be the most understandable, here is no longer repeat. Let's talk about the applicat

1. First prepare the document containing all the provinces and cities, and drag the document into the Xcode we built. 2. Then create a new path nsstring *path = @ ""; Then drag the provincial urban documents to the @ ""; 3. Before sorting, we first need to filter the idea: The problem with this answer is how to load the dictionary into an array, and then load the array into the dictionary, so the key point is how to provide a small idea by nesting e

Question: hdoj 2874 Connections between citiesAfter the war, some cities were destroyed. The graph is not connected, so you can find the distance between any two points,Analysis: It is obvious that the LCAHowever, the graph is not connected, so we need to perform each vertex in Tarjan. Then mark it.In addition, the question becomes vector. It seems that we will learn to use arrays to simulate the adjacent table in the future.AC code:# Include Hdoj 287
