Q: You can use one of two trick answers to answer a single question. One trick can only be used once at most, and the maximum number of questions that can be answered in a row is allowed.Idea: I first thought of the maximum matching of a bipartite graph, but I was totally confused. I think there are two trick options available for each question. It is obviously wrong to use this to split the points and create a graph ..The correct solution is to use each question and each trick to build an edge.

The model of the Bipartite Graph is an adaptation of a classic question. As shown in a graph theory book, there are n people and M positions, and each position can only be provided to one person, while each person can only be qualified for a limited position due to limited ability, ask if there is a way to make everyone have a job, and if not, how many people can provide a job at most. If you have read this classic question, the idea of this question is as follows: Consider n questions as N poin
