Conclusion of the ACM/ICPC Asian semi-finals Mudanjiang Station

I also had a general level in the training team. This school had an unprecedented eight places. As there were only two teams in junior year, we were entitled to 13 and the number of places, the team leader is very excited to ask more questions about OJ. I and tyh, sxk, and doubleq are lucky to have the opportunity to participate in the Asian field competition in their sophomore year. In the Mudanjiang division, I joined sxk and doubleq to form a rainbow team. We actually went to Zhang Xianzhi for this round and increased the competition experience (plus 2333 of Public travel expenses ), but when we really came to the arena, I did not know that I was so eager to get a brand. On the first day of the warm-up match, double quickly got into the water. I kept getting questions D and came up with a linear solution, but wa... I felt that my algorithm was correct. Double said that if the input is invalid, I Would output 0. I didn't think I would be able to cope with this situation... The result is wa to death... After the game, I discussed it with others. This is the case .. Qaq... Rising posture, input is still illegal .... Ah ..... Then the next day, the official competition started. As soon as I got the question, I began to feel nervous and panic. As a result, I got question a for half a day and didn't understand the above... Later, I calmed down and thought about the question TM water .... Decisive 1A... however, due to my nervousness, question a was very slow. After reading that many people on the market solved question I, I was very long ..... I did not understand it once .. Then I asked sxk what it meant. I almost understood the question. We started to think about it as complicated. I thought about a simple limit, I feel that the limit that I don't want to be so long is 0, but I can't think of anything else if I'm not 0. I decided to choose 0, and then I had e to solve it, I forgot how to ask E... Templates are not powerful either... It's really depressing ..... Fortunately, in the doubleq template, there is an indirect e-seeking method, decisive 1A... at this time, continue to write d in the list .... D. I have no idea... Doubleq told me that he had come up with a formula to combine mathematics... Then let's start d in the next three hours .... Wrong posture (it was later found that this is probability DP... Depressing slag has never done probability DP ...), Then I found K questions in the last hour or so .... Greedy... I thought about it for 40 minutes and thought about it. I typed the code in 10 minutes... I hope it will survive... Then .. I wiped wa... At that time, I felt like there was no such thing... No time to think about it ..... If you have k questions at the beginning, the probability of a loss is very low .... This time, the game rose, and it won't take three hours to solve a problem .... Qaq .... I was looking for a group photo with bin and Jiuye .. I'm sorry to ask for Qaq if it hits iron ........ There is another month before the Guangzhou division. Have a good question... I hope that is the same .....
