First ICPC, as with the first CCPC, but really a pity.
After his game feel uncomfortable, uncomfortable is not yet hold bronze medals, but that can not out of the question a very strong sense of pity.
The opening is still possible, by a burst of discussions on the law A bold speculation, and then out of too, then Kun Kun K is seen computational geometry problems, they engage in K, I read a list just will not get to know H read C, a C began to see several pictures, thought it was a problem, but do feel after reading it, they exchanged ideas with at +1. Kun Kun wrong then the situation got K, some anxiety, but after a C, etc. A +1 out of the question, Kun Kun also find an error, then K title followed before. Until this time, probably after 1 hour and 40 minutes, it was quite smooth. Then +1 J told me a question her reasoning, then I feel able to build a map, and is a cost flow, determined to try, and +1 together to engage with the question H Kun Kun. Then there have been the wrong idea, think again with a J H almost, so they let up the idea.
Next will be a problem, J title Qiaowan a result of cross-T, and then my mind instantly thought dijkstra optimization, as well as zwk cost flow, and then not used dijkstra optimization of direct copy board, samples are run, but, I do not know why, then wasted a bunch of time, and finally tried it out of zwk cost flow, the result has T, and then we feel that this is not a problem of network flow. In this way the title H +1 and Kun Kun launched a conclusion, but a cross the wrong. Then the question is caught in a card, surrounded by all kinds of Tucao H question, mentality we have gradually been affected, and there about 40 minutes when I suddenly thought, while Kun Kun also happens to me had a bipartite graph, I they immediately identified under the n- 3 complexity, did not run, that is, maximum weight bipartite graph matching, hateful my hand speed ah garbage, etc. Qiaowan are still a few minutes, and then the sample had not been looking in the wrong, the last few minutes have gradually panicked, and then finally did find out.
And so we ended the gnawing bread only to find it a place of written j i, ah ah ah ah ah really, woccccccccccc, while the next team after a hearing, said Kun Kun found with +1, H title only a thin one special sentenced to 100 of Figure game ,,, borrow some easy-going elegance of the team, he deserves to marry the princess.
Alas, uncomfortable ah, ah uncomfortable, end of the game that a group of half an hour was really uncomfortable. But also felt the problem, not enough focus on thoughts, vulnerable, but I have to upgrade my knock code speed.
Nanjing has passed, the next step is Xuzhou, we do not say what Paul copper teams, and want to take that gold, we are the gold medal team, change their attitude, Xuzhou battles, we believe everything will have a good result.
And with the blast forward, we should also pay attention behind.
