Before the game ：

Summary ：

As an information major student in a medical college （ Algorithmic chicken ）, Also as our major The first To participate in ACM The player , I want to sum up the experience and lessons of this competition .

emm, Although as an information major , But the race about algorithms , Our past （ In fact, the Information College of our school has just been established for three years , Ha ha ha ha ） Or take part in Blue Bridge Cup Mainly , About this choice to sign up ACM It can also be regarded as our college's way to program design competition Take a big step .

Because it's the first time to compete , therefore Before that, there was no systematic algorithm training , But we started to apply for a conference room for one month's algorithm training one month ago , The aim is to better meet the Blue Bridge Cup and this time ACM.

We agreed to train every night of the month 18：00--21：00 This period of time is the algorithm training time of the three of us .（ Obviously, the preparation time is very hasty , In addition, it was also delayed for some time due to the soft application of the project ‍️）

In the game ：

Summary ：

ACM The competition system is the topic All in English , But you can print your own materials and carry an English Dictionary for the competition , The competition time is usually 5 Hours ,12：00--17：00, The competition uses io system , The results will be displayed immediately after submitting the code ,ACM Each submission will show right or wrong , If AC If you drop this question, you can look at the next one directly （ No, A You can also look at other topics ）, During the game, there is Unlimited programming languages , Although we reported java Group , But during the game, we found that we can use java It can also be used. C, You can also use python, For example, our first question uses java Write timeout , And then use C Write , The system says the format is wrong , Finally, it was replaced by python To write , Finally A It fell off .

In this competition , We can grasp the rhythm in front of us , The first few questions will soon A It fell off （ Because the first few questions are not very difficult ）, The later problem is because our algorithm reserve is limited , Are limited to thinking , But the code can't start , Unfortunately, the first question wasted a lot of time because of overtime .

The most pity is that there is a title of candy behind it , The idea has been very clear （ Is to use double pointers to A The subject of ）, But because there was not enough time left , Some details were not optimized in time , Resulting in the last moment of time Or not? A fall , It's a pity . So we should try our best to solve the problems we can do in these five hours A fall , Otherwise, it would be a pity ！！

After the game ：

Summary ：

After the game , The whole person is a little tired , First of all, because the duration of the game is 5 Hours , Try to stay focused during the game , Then there is the poor sleep quality in the past few days of the game , So the first thing after the game is to lie in bed .

At seven in the evening , The closing ceremony of the game officially began ,（ Because of the epidemic , All the activities related to the game are put online ）, The competition is followed by the awarding process , unfortunately , Only got the Participation Award for the first time , According to the ranking, at least A fall 6 topic To get Bronze medal , We see our own gap , The only thing you can do next is to improve yourself , Bring yourself closer to a real ACMer The gap between

ACM Entry learning route ：

ZOJ There are real questions over the years , Interested students can go to see ！

summary ：

Although it's a pity that I only won a Participation Award in the end （ Pure is reasonable ）, But for me , In this one month algorithm training , I did learn something , Next, I have a long time to think and learn algorithms , Fight again next year ！
