③ Reduce code duplication: abstraction can reduce a large amount of code. "generic" is a small part of abstraction, so "generic" must be learned.
④ The Only Way to object orientation: the three elements of object orientation are based on abstraction, while "generic" is a small part of abstraction. Therefore, "generic" is the only way to object orientation.
⑤ The beginning of architecture: to do a good job of architecture, object-oriented must be mastered, a
Idea: I didn't know much about this question at the beginning. Then I thought it was the biggest bare-cost stream. Just do it after creating a picture.
However, the question is that binary matching is used to do this. Because the weighted matching method does not, the maximum stream with the minimum cost can be used directly.

There are some cars and some people who repair each car, giving each person the time to repair each car, and asking everyone what the shortest average waiting time is.
Idea: Remember that poj has a question that is similar to this one, and the practice is the same. When a person repairs a car, we only consider the impact of his or her time on the time of the person who repairs the car after him, therefore, we only need to consider that each car is the last few repairs, and then we can simply bu
following n lines represents the matrix. you can assume the numbers inThe matrix are non-negative integers and no more than 10000. The following n lines represents the height of each grid. The heghts are also non-negative integers.
Output
The maximum point zhouguyue can obtain after he travels at most K times.

A racing competition was held in space. There are two flight modes: the first is to fly from a normal road, but only from a small number to a place with a large number; the second is to go directly, but it takes a fixed time. Ask how much time is required to traverse all vertices at exactly one time.
Idea: billing flow. Split each vertex, s to the start point of each vertex, and the cost of connection to each endpoint is fixed, the original edge of the graph is connected from the start point to
