I read the problem set and it’s nice. I found the problem K is really elegant one and also found that Problem D is easy to solve. I think it can be solved with some experimenting. If I could give my team advice now, I want them to try the problems that everyone is solving.-Jorge Perez, Universidad de Chile
After I read the problem set, I have to say it’s balanced with 3 easy problems, 3 medium problems, and 5 hard ones and I liked the problem G the most.-Ho Dac Phuong, University of Engineering and Technology – VNU
I found this year’s problem set is hard, although this is the World fFnals and this is our first year and our first experience in the Finals. We didn’t solve anything yet but I think we’ll solve 2 problems. -Pau Suan Mung, University of Computer Studies, Yangon
I really liked the problem H. My thoughts on this year’s problem set is that it has some hard and trivial solutions and ways to solve it, but it’s easy to implement and code. .-Mihail Jianu, University of Oxford.
I didn’t read the whole problem set yet but I enjoyed problem K. I would tell my team to stay working solo – in parallel – until the third hour in the contest then tries to solve the problems in a group. -Mihai Calancea, University of Bucharest
I found some problems are relativity simple and easy. Our team took the first place for quite some time and I think they’ll get a high rank. We’re aiming to take a colored medal this year. -Jan Madey, University of Warsaw
I we reached the 20th rank, and I’m really hoping we could break the Arab record. That was at 55th Rank. That would be an amazing achievement. We’ve solved 4 problems till now we I’m sure we could more. I liked the coaching system and the ability to see the contestant. That will help me to give them better advice on something they did wrong. I’m feeling how nervous they are down there. They are sending a lot of wrong answers before getting the problem accepted. -Sufyan Almajali, Princess Sumaya University for Technology
