Question: In a graph, the vertex weight indicates the energy value that can be obtained from the vertex. positive and negative. A person starts from 1 with 100 points of energy. ask if there is a solution that allows a person to go to n when the

Question :( I didn't understand it at the time ...) There are n princes and N girls. Each prince prefers several girls. give the numbers of the girls the prince liked, and then give a perfect match between the Prince and the girl. ask every prince

Question: There is an apple tree. The root node number is 1. The edge weight is the number of apples on the edge. the maximum number of apples that can be retained when x branches are retained. Ideas: Tree DP. The DP [I] [J] indicates the maximum

Question: (the questions written by Europeans themselves are different... all kinds of sputation... I think I'm confused) A directed graph has a source called ccs. It calculates the sum of the shortest paths from CCS to all other points and the

I didn't understand what it meant when I made this question. After a while, I finally got it. In fact, this question is relatively simple, and I personally think the description is not very clear. Description A basic problem in computer science is

Question: Returns the cut point of an image. input is slightly special: first enter the total number of vertices in the graph, then each row first gives a vertex u, and then gives a series of vertices connected to this vertex (the number is not

Will finally be executed? The answer is no. If the system is executed in try. exit (0) will not execute finally any more. When finally in the daemon thread exits all non-daemon threads, it may not be executed. What will the following code print?
