Second year, and probably the last year.
To avoid a repeat, sum up experience and lessons.
Big semester, nmh I suddenly find that they have to train with the team, when we do contest is one of a set cf, beginning one week do two sets, then set, and then again direct a pigeon.
Then play four provinces and the provincial tournament game, which is in May.
Provincial tournament, the last President of the trees + rmq title, I wrote, inexplicable wa, finally did not find the reason, the second prize of ending.
Race four provinces, a similar binary split title, three people together to do for a long time, finally made a backpack dp, because I do not do for a long time, forget this thing also set the initial value, wa into sb, third-class Award ending.
Summer training, pre-fight pulpy, among a number of games is acceptable, and sometimes can take rk1, late knowledge points less likely, because of the knowledge I took over from high school only noip (probably did not even think of the University will continue play algorithm contest)
September several games network game, we had agreed on certain days one week and do another night a problem, but do piecemeal, very few have any effect, I practice also to learn something new, not skilled I did not have the opportunity to spend too much.
End of September ccpc Jilin station, the opening seconds nmh a sign, fets and a second sign, this time I've been watching a gold sub-title, suddenly, fets said he would do a similar solution of the equation of three geometric problems , and then the a
At this point we would have the advantage of very full, but I was straight out of a two pot, the pot first, mistakenly "1/2 kg" as "1/2 weight", cause this problem turned into another title
The second pot is a probability dp, it seems that this process can continue to go on, I pushed the wrong, so he turned into another solution.
The most frightening thing is that the two questions I wrote a long, long time, leading to the back even see the problem, do not modify time, the first pot was teammate repaired, but the problem has always been the probability dp wa, copper tail end.
Then eleven, tom find a set of questions every day, I remember our team and the level of the ear fifty - fifty, sometimes in front of the title do relatively quickly, it was thrust on the back, fell to the penultimate or final third from last.
The most impressive game, is icpc Nanjing Railway Station.
Warm-up match, I remember very clearly, the title stuck a ac automata, because we basically did not how to use it done problem.
Official race up a question, a problem similar to the game, the best strategy is "disconnected from the middle," as long as there is a break not open conclusion, the two teammates discussed the topic for about 20 minutes, pay up, how to pay how wa, later found the cause: forget sentenced n = 0
At this time has passed an hour, I also saw a one-hour question, is a prime number to calculate the contribution of enumeration problems.
I write more slowly, but also for insurance, write up is a direct circulation of all numbers, so direct t, and changed several optimized over this problem.
In this process, the two teammates discussion Another problem to flow through the network
At this time, probably less than two and a half hours left, before us is a triangle number of questions and do not know what is a suspected problem in three-dimensional geometry.
The number of triangles questions, two of his teammates do, nmh discuss this thing into two cases, he pushed one kind, fets push another, and so he pushed over, ask fets, fets say no clue, he said not good at math. . .
Because we will not do another title, we speculated that it was "center of gravity" because we only have three-dimensional center of gravity of the board, so I became a knock on board, they push the triangle problem.
About an hour later, they reached a conclusion: n is related polynomials, the highest entry in the n ^ 4, so we try to determine the coefficient of small n.
Unfortunately, we are here to push, and it is hard solution of the equation, and there is a push n wrong, which led to this formula does not fit anyway on.
Finally, the two questions we can not, we unanimously came to the conclusion: cold.
The most dramatic is, tom ran over to tell us that there are cards, I think that something may be a problem, sure enough, the host read more than a few names, and we happen to be iron first.
Three Questions also have a large copper, if we are a little less like a time penalty, but unfortunately no going to eat.
Later, faced with a problem: no teammates. Refused to heart tired.
Fortunately April, finally put together a.
Provincial competition, and because the test crash, did not go. (Xin deficit did not go, otherwise the operation seems to be a teaching secretary became engaged Kuangkao?)
Race four provinces, the whole thing was a bunch of annoying, but fortunately good, and considered to take over the provincial Yellow Gold game.
There are two problems, first, the warm-up match when vector.size () - 1 will turn into a very large number, let me drink a pot, the fourth question did not launch, at first I was wrong range.
Second, when the front inscribed finished, everyone did behind the questions the ability to open, and waited for an hour.
I feel there are three main issues:
acm test of knowledge, too broad, and some knowledge points if you write the unfamiliar, or not at all, is likely to be cool.
Another one, a lot of questions tend to analyze its nature, often without a thorough analysis of missing something crazy will contribute penalty when the state of mind to engage in collapse.
Another, hand speed is too slow, and some time to write and think not a thing, it will waste valuable time machine
