Xdu_rainandbow Anshan wrought iron in the mind

We as the weak school Xdu seven team (senior one, Big three or four, sophomore two), originally did not expect to go out this year, the result is good luck, the school got a few excitement places,

So we excitedly successfully applied to the place of Anshan station, um ... can go out for a trip.

However, after all, we are too weak, we feel obviously is the iron rhythm = Oh, just Anshan is the famous steel plant location, and then really the blacksmith

Before the game to do a few simulations, last year two games are iron, but the distance from the bronze line is not small = = then did the Mudanjiang synchronous race, just over the bronze line several, plus

The seniors took two silver medals and encouraged us, so we got the hope of winning the medal.

The first time to travel, or quite excited, under the plane will first run to Shenyang stroll for a while, the tragedy is Shenyang Forbidden City unexpectedly closed, night rushed to the railway station, a arrangement

To Anshan, took a taxi to the organizing committee designated sanatorium. Then ran to play cards with seniors, back to the room teammates said found the bug = = Frighten my clothes did not take off directly to sleep.

Three of us did not bring a computer, so the next day to go to the Internet cafes to play a problem, the result in the beginning to play DotA. I have not written a question for two days, this may also be my opening state full

One of the reasons for none.

Saturday warm-up, saw a long day only to find the question, after the check-in question on the dumbfounded, the remaining three questions are no idea, so the warm-up soy sauce, plus a variety of

I heard that clj to be a very sick topic, I actually thought that the official tournament is a two-problem hand speed =

The next day the official race. Because the hotel location is too remote, six o'clock to get up is also pretty spell.

After the start of the formal game, I quickly went through a lot of problems, a look at the water problem, teammates quickly knocked to submit, unexpectedly back to WA, I looked at the side also did not find errors, thought is the precision asked

Question, he changed the submission again WA, at this time I because the subconscious mind has always thought that this may be a speed race, check-in question unexpectedly out so slow has scared silly. And then I saw it.

int, always feel int is not reliable, teammates also come to carefully see really burst int. Teammates hurriedly change the commit, 22 minutes finally return yes.

At this time to see the list, there are two teams, several teams over E, and then we began to look at E, the first eye no idea, the results soon a big wave team out of the e question, and then I

We also underestimated the strength of others, thought that the team so much, should be a messy problem, the result has not thought, and then teammates began to look at other questions, I like a fool sitting in that

Chaos thought, after a long time finally thought of a more violent thinking, carefully think is a three-dimensional DP, calculate complexity seems not to time out, so I hit DP, Knock Good and debug

Half-day, submitted back touching WA, and then debug for a long time, the teammate said to try the greedy of D, so he went up to write, quickly write better than the example, and then WA. This

When the game is filled with balloons. We are still poor, and at this time I really feel the pressure is very big, suddenly an epiphany. Found all-1 of the Special award was not considered. So the machine

Changed, 122 minutes to submit finally return yes, but still failed to enter the bronze area.

Carefully looked at the list, found that the copper area is still a lot of 2 questions, feel three should be able to stabilize copper, so we made a stupid decision, that is, three people to see the D problem. Begin

or according to the greedy thinking, then we all feel must be greedy only example, teammates think of the enumeration interval method, but simple enumeration complexity is too big, this time three people

It was a pity to start sitting again, wasting a lot of machines, and not using this time to start knocking on that simulation question.

After sitting for a while, suddenly found that the enumeration interval can be O (1) recursion answer, the total complexity is actually O (n). So on the machine began to knock, knocking good or dead can not be a sample, teammates hurry to go back

Push the formula, found that I have a place sign and sign wrong, changed a bit, after a sample. 237-minute commit returns YES. We finally had 3 questions before the list. Last hour, over.

Many of the C problem we have no idea, found that B simulation there is hope, so change the captain to write a simulation, but after all, is not a normal simulation, to 10 minutes left before we finish the simulation

, and then changed a few examples, submitted, returned to WA, and then soon the game is over.

Finally, we ranked 3, 108, to two hours of the gap between the success of the iron, seniors of the Xdu_fate Team 4 questions 1Y to get a silver medal.

After the match, we went to Dalian to travel one day, Dalian is really beautiful, but I always feel missing something.

Summing up our experience in the iron, the first major reason or training time is too short, insufficient strength. Secondly, due to various reasons, the opening condition is too bad that we are at the beginning of the penalty

Has a great disadvantage, and finally because of the lack of experience in tactical error, no use of spare time to knock on the big simulation, although not necessarily a little bit more can make that problem, but

At least a little more hope.

Well, the last is to be inspirational, hit the Iron Bull is not no, we still have hope! With only an Anshan quota this year, the 2014 season ended in the iron,

Let's fight again next year!
