"The most effective way of learning algorithm is more questions, and secondly to pay attention to not only look at the surface, to try to understand and learn its nature." - Hong Huadui
Today, Comet OJ share is 2018 CCPC-Wannafly Winter Camp, topic, lecturer, ACM Gangster Hong Huadui (SkyDec, Peking University School of Information Science and Technology, 17 students won the ACM-ICPC World Finals 2018 third gold medal ).
Comet OJ: Hello, Hung teacher, I was Comet OJ ( cometoj.com ) operations manager, thank you for a guest interview education Comet OJ centroid. What is your participation in this camp set up the original intention?
Honghua Dun:
Hello everyone, I am a Hong Huadui from Peking University. Mind the words just wanted to share with you some algorithm contest some tips to make everyone happy playing.
Comet OJ: What is your role in where?
Honghua Dun:
I have almost the same teacher role it is out of the question, the work of about lectures and the like.
Comet OJ: What do you think the significance of the game is to carry out or winter camp?
Honghua Dun:
The Camp probably have close to 400 people or so to participate, I think the meaning is to let more people come into contact with this race, because most people may not be able to receive training system in school, they come to the Camp, you can get centralized training.
Comet OJ: Do you think CCPC-Wannafly Winter Camp and other camps learning algorithm What is the difference?
Honghua Dun:
First Camp is the public nature of this, this is basically all the camps are not the same; secondly the Camp there are some of the more innovative places, such as divided Div1 and Div2, I think this is the biggest difference.
Comet OJ: you have any good ideas for programming and algorithms to enhance literacy can share?
Honghua Dun:
I think the most useful way is to do more questions, followed by the time learning algorithms, learning not only the surface, to try to understand and learn what its essence yes. The main way I feel it is still more questions, do not do anything, then no good title.
Q: Do you confront lectures and educational centers of the game platform provided by this Camp OJ Comet ( http://cometoj.com ) What experience? Any suggestions?
Honghua Dun:
I think the overall experience is very good.
Because Comet OJ interface is very clean and evaluation is also very fast.
But there is a shortage of a few places:
I used to have a habit oj, I open question when I put all the questions to open a new tab. But this seems not take oj new label, it makes me feel somewhat incompatible. But overall, this is very good oj, oj good because I think a more important feature: the interface is clean, so do problems will be comfortable.
Also, the problem of feedback works do not seem too good, the game is the problem of feedback. Secondly, each question had not even open a new tab feeling a little uncomfortable, there is no way one-time all questions are open out, and then look at a road point in the past, each time for questions to be switched inside look at oj.
Comet OJ: you have anything to say to participate in the Camp campers?
Honghua Dun:
I think the Camp for all of us should be a memorable experience it. Although some students will feel the topic is very difficult course is very difficult, but in fact these are also very important experience. When you encounter these difficulties, we will have an incentive to work. Finally, I wish the graduates later, the future is bright.
Comet OJ: how is your year into a pit contest?
Honghua Dun:
I was initially into the pit is in junior high school, the teacher let me go with seminars related to the algorithm contest organized by the school (similar interest groups), but participants forward to attending the start into a pit.
Comet OJ: Do you think other people and to teach their own learning algorithm What is the difference?
Honghua Dun:
I think the biggest difference between teaching and playing the game is: you must expect to play the game as simple as possible start, teaching is sometimes as simple as the question was more difficult to say, some problems but it is easier to talk about. In short, I think teaching the most important thing is to try to explain to understand, this is the most important.
Comet OJ: What is your message to CCPC-Wannafly Winter Camp for that?
Honghua Dun:
I wish Wannafly Camp better and better.
This concludes the interview to ~
I remember the day after the end of the interview, is already more than 19 o'clock, we did not eat dinner, and then from science and technology building small step Northeastern University sprint direct rushed to the Engineering Building, because after half an hour is the solution to a problem - the evening's lesson
Interview Date: January 2019
