Copied from space, although it has been over one months, fresh memory
It's kind of a re-picking up this blog
Just begin
Looking at a group of Daniel and the team-mates male gods of the province to summarize all out I finally can not resist loneliness to do a journal Express lyric Good
The first time province race mood is very excited also mixed with a little tension actually most want to spit trough is the food really really real really eat not full ... But thanks to our XH teacher for the X-and X-Force, we didn't have a lot of time for lunch. x cows do provide a great deal of energy (I really don't have to advertise, you look at the code.)
Back to the point is to do the Journal of the Nineth early seven o'clock set from Zibo to sleep to the big Qingdao in fact, in a sense, this will be my other home, um to the big noon head of the South Gate really domineering our car alive from the south Gate to the mountain branch northwest side of the campus hotel because only the south door can be opened to traffic ... And then we're staying at the hotel leader, and the three of us are going to be big.
also drunk. Lunch... Just remember that chicken leg ...
Hurriedly finished lunch finally entered the theme from Northwest side walk to the southeast side of the computer academy to attend the opening ceremony of all kinds of groove points is not listed the most clear is the ACM Society president and the same as Y pa referee ym my gold medal y~~
Then it was the pre-season and the first team had to dismantle the problem ... Well, it's a game, too. Hey, everyone around you is torn down.
A one-off sample cases Urealyticum equation decisive first pass back to a page immediately found red fruit sum three big letters formula immediately blurted out NS lightning theft Bell when the potential 4 minutes 1Y first time provincial first Yes and 1Y immediately confidence doubled
B
First N and note range with unsigned long (n+1)/2 Note to determine who will first divide the parity 2
Back to the feeling C is not difficult I use my slag English to the side slowly key NS and YF together to see D problem read C to understand after not come up with a good algorithm to the test instructions speak to NS and then NS to think algorithm I asked YF d the main idea about a read feel is similar to the law of the NS for a time also can not think of the C algorithm to study the D NS according to Pushed to the formula knocked out and then I was on the side to calculate the feeling of violence must t then think of the way the seniors have tried and true is the table ... I took over the table knocked half NS suddenly said c he measured a few sets of feelings have been output 1 seconds knock six mesh a pair of submitted 1Y at that time excited almost called out now think of it is also a sense of a spell according to NS said opposite Mountain Big official team game end still in push formula silently worship under the truth said this question a very look face ....
C
N number asked whether there is the number of M (1<=m<=n) and can be n the whole of the existence later with the seniors learn to say is the pigeon cage theorem will n number of N to take the remainder if there is a remainder is n then the number is not 0 must be able to remove the residue of m number of the sum of n that is the number of M and just N
Double 1Y morale is stronger with the hands of many years of exercise speed to hit the third 1Y of D
D
Give a set of series 110100100010000 ... the law can be imagined and then give a K q K number is 1 or 0 1 position has 1 2 4 7 11 16 Press this to an=n equal margin as the law of the interval is easy to play out the array and then directly output the number of the corresponding position to listen to some of the bull team The normal solution to this problem is to find a regular column formula into the solution (just tried to really list out!) Good fun) If the number of each item minus 1 can be obtained 0 1 3 6 10 15 (arithmetic progression with a tolerance of 1) then you can get the formula 1+n* (n-1)/2=k as long as K satisfies the formula K position is 1 simplification n^2+n-(k-1) *2=0 to derive n= ( -1±sqrt (1+8 * (K-1))/2 if 1+8* (k-1) can be opened and followed by an odd number, the K position is shorter than the 1 code.
After that is the long card problem I card a NS card E a formula has been very clear hundred is determined to be in the output of the format of N-fat WA mainly in the negative root output sign and fractional output format pit ym that a out even 1Y giant giants
A
Unary two equation output format it's disgusting. The idea is very naked to judge Δ output a real roots two real roots or two negative root to wait to add the game not a is uncomfortable ...
I also see the E-Question of NS I look at the note it seems that after the end of a few team a off may be a variety of multi-comment wrapping and so on, and then looking at a big two giant talk about it. Note that the comments in the string cannot be deleted. ，。 Wait for the plus question
Overall, the status of the warm-up is very good last three 1Y ranked in the silver medal District 17 can only say make it. Or too weak during the host line dropped once was also drunk. But fortunately, the warm-up was early detection.
Dinner at night (chicken legs are not ╭ (°a° ') ╮) and then wait for the XH teacher and ZXW teacher to open a small will suddenly find patronize to do the problem forget to brush the server. Sure enough, it's too young. Xiao to share his record can run 8000w times/s has been expected to some of the problems may tle ... Then they went out for a walk and had to say that there were few people at the weekend in the mountains. Or my home is more comfortable after all, there is miss cough cough ... Someone wants me to taste Laoshan Coke really didn't find wait for you to bring me next time
Night fighting to sleep with the NS in the middle of the cough cough .... Very simple sleep.
The next morning was awakened by the alarm bell by the bed Luo back pain. Maybe it's not customary to sleep somewhere.
Seven points to eat meal coupons to dinner again thank XH teacher x Cow!! and the X-Force frame plus a mountain of a volunteer sister paper postcard (everyone has a share) the word is very good (better than me ...)
)
Finally, to the battlefield, after a long 10 minutes, the test bag was thrown over and looked at the countdown for a second second, and it was pretty cool.
00:00 YF Quick to open the letterhead note is really demolition! It's called an excitement. The heart still plop, but then the reflection found that this is a big taboo to do what is still the best of the Normal Heart
As usual, I abcd NSEFGH yfijkl ZXW teacher said the night before the University of a check-in question should be a really a question a look is red fruit fruit water problem! In peacetime is definitely read the title plus 1Y five minutes less! Yes, I'm in a mess. It may be the first time the tension of the provincial race may be to get the problem after the excitement of the heart did not immediately calm the original can read the question I read not less than five times Yes five times and also read wrong! 1W I'm trying to stay calm. I know that NS and YF, like me, are trying to keep an impatient heart as much as I can, because we all know that a sigh may affect the whole team's entire game.
At this point, NS said he had a train of thought, and then I went aside to let him knock later I really can't read a question a look at the list C also have a lot of a and then a look to determine is game in the first reading is the question of stone to see can take 1 or 2 do not know where the confidence is this confidence or more should be said to be conceited and a 1W contribution later Now else forgot to change the line to complete the submission of another w! I don't know where the courage is. May be a continuous W head & to now also for their own time the game of reckless remorse,. The position of the NS immediately after the G-Question 1W This period I read the A topic study n times to find out at the beginning unexpectedly did not notice to be the height of the order. The idiot thinks it's already lined up. I actually thought the height is useless I also hesitated two not to pull a few thought is a bluffing the thing result oneself is also bluffing to take a team of momentum!!
Carefully changed to two members of the structure of the sort of cumulative output 2Y This is my first time in the province of the biggest scar my ego dragged down the team deeply to my closest two teammates Jxn Lyf apology should have been very fast 1Y of a problem
A
n individuals sorted by height, press 1 2 1 2 1 2 reported 1 of the Red Team 2 is the Blue team asked which team members of the overall weight of the largest
Then I went on to study B YF said J questions have the idea of decisive let the position to his knock submitted 1W let people angry is just handed over the referee on the issue of the revision of the scope 10^1000 printed 101000 ... It's a meow! It is also strange that did not have a look at the problem and guess ... I am decisive with NS said large number on the Java rinsed finished writing commit 2Y
J
Male and female group to attend the ball a man with a woman asked can be divided into 11 teams to enter the number of boys a girl number B judge a==b? && A%11==0 after the game with the team to think that you can enter the string and then bitwise 11 to take the new skill get√
Then read the B after reading and found a burst of similar business problems that is more complicated than this problem is to simulate the auction process and then follow that idea to use the linked list to do the results submitted 1T ... Immediately think of using an array to optimize the NS said C he found that in addition to 1 2 of the rest are opponents win for two seconds decided to use three face to spell again. Quickly write code Submission 3Y Unfortunately I have not the day before the excitement of the rest of the only regret ...
C
Take a stone one or two but only the adjacent stones into the ring arrangement is the first is also connected but if go to 2nd 1 and 3 is still not adjacent YF later said that before the similar game but at that time, the problem is not ring the problem take the center of a chain (the number of stones is odd) or two (the number of stones is occasionally) on both sides of symmetry so always is the initiator Win and this problem because looping take the head or tail stone after the chain, so in addition to 1 and 2 is the rest of the win
The feeling of our team doing well in the game is that each time a question is submitted, the results are then knocked on the other questions to cushion the tension and save time.
I knocked on the B, and I hit half and found that fatal error. Multiple input while less write ' ~ ' Loop can't stop! Code changes are changed to simply finished he measured a few sets of examples of the decisive 2Y submission. After seeing yes, my first reaction was not to loosen my heart's guilt. I know this emotion will affect the continuation of the question of forced pressure down to continue to see the problem
B
Small analog First enter character b for bid Q output only once in the price of the current bid the lowest price C is to cancel a bid see some big God said with Set soon a out. I think we should fill in the STL. After the list time-out, use an array to mark a price occurrence only once in the list and then traverse the list output.
Later, I think about the feeling of G and H can be a short topic very brief general first read the two questions very similar g is to ask the cubic number H is the square number three people agreed to solve the square number of the cubic number and then I began to study the square number just started thinking there is a problem all the way to hit the table and then constantly traverse Later I thought of the pigeon cage in the warm-up of the feeling can use similar ideas at that time to split each number (after the game is known as decomposition of the quality factor ...) Out) at that time did not want to first use the prime number of sieve sieve prime number of direct violence to eliminate the sum of squares in each of the numbers and then use the array to mark the number of non-square number of occurrences and then multiply to find the combination of the code is more chaotic even after the G problem can not be a (one) WA to lose confidence when Finally see the green ... 5Y
H
To the number of groups asked how many (Ai,aj) meet the Ai*aj for the square number of the game with the cottage decomposition of the mass factor a ... Now we understand that using prime sieve is the right way to decompose the mass factor. After the game and then the prime number sieve also will be a new skill-decomposition of the quality factor
Because the H problem method is adding the G problem data card dead write G question either WA or tle but still insist on writing to the end of the game ... The last few minutes have been handed ... WA period NS Read L problem unfortunately time not enough after the game asked seniors said is strong connectivity ... Shenmegui only blame himself too weak. I admire the NS did not touch and then I slowly groped to write I am relatively lack of this spirit of exploration to the NS learning
The first provincial race ended up like this. 36 dissatisfied you said I was listless. It might be a bit. But it's more about self-reflection. Come out to see the world really can grow and learn many times the defeat also can let me steady down ABC three times of the second WA times of the Black dragon or the heart is not strong enough and too conceited otherwise will not five questions bottom ... It's the win their hearts. A solid steady deepening algorithm data structure knowledge will not immediately learn to drag and hold the crown will be heavy!
This is the journal of the game. But my ACM trip just started, but I know there's not much time to say humorous has been very grateful to XH teacher led me into the SDUTACM this big family that night memory is clear I wander between ACM and software development is also very grateful to CG teacher understanding But it was really naïve to think that you can use both ACM and software development as XH teacher said to do one thing will be fully invested otherwise there will be no results and also to teammates, ACM family and my own disrespect this is very unfair to the teammates at that time I do not understand the simple thought that both sides can scruple After a few months of ACM, especially after the winter vacation training, I slowly realize that this is a long road you do not have the leisure to see the scenery along the way, not to mention also in the development of the ACM and the two roads on this road is lonely work hard not to spell it by your own decision but not alone Because there are countless people with you on the same road and there are a lot of people more struggling to run a little rest will be a mighty army stepped on the Refueling bar program apes will someday be able to spell their own glory!
Finally, I thank someone for their constant encouragement and support. (°?‵?′??)
