Though Some survived cities is still connected with others, but most of them become disconnected. The government wants to build some roads to connect all of these cities again, but they don't want to take too much.Inputthe First line contains the number of test

write a program that would solve such problems.The input consists of one to the data sets, followed by a final line containing only 0. Each data set starts with a line containing only a number n, which is the number of villages, 1 The output is an integer per line for each data set:the minimum cost of aacms per month to maintain a road system that C Onnect all the villages. Caution:a Brute force solution that examines every possible set of roads would not finish within the one minute time limit

Recently, from data analysis, many keywords need to be matched from a large number of short articles. If the brute force find is found, the CPU becomes a bottleneck, so I thought of the AC automatic machine. The AC automatic machine is a classic data structure for multi-mode matching. The principle is to construct a fail pointer like KMP. However, the AC automati

Introduction :This article is the blogger's own understanding of the principle of AC automata and views, mainly in an example of the way to explain, at the same time with the corresponding picture. The Code Implementation Section also gives explicit comments, hoping to give you a different feeling. AC automata is mainly used to match multi-pattern strings, which is essentially a tree extension of the KMP al
