Training in the second week of summer vacation on July 24, 2022

This week, I finished reading the information Olympiad one pass improved version , By the way, I finished the one-stop problem of information Olympiad in Los Angeles .USACO I didn't do much of the problem .

One ： First, let's talk about how we spent this week

The mobile camera used to open the live broadcast is broken , The live broadcast cannot be opened ,

  When the mobile phone is repaired next week, the live broadcast will continue

I still studied advanced mathematics this week A, probability statistics A, Additive algorithm . I wasted a day on Saturday , On Saturday, my cousin came home from the factory in rotation , He and I play hero League , I spent a day with him .

This week, I was in the Information Science Olympiad during the day , After learning probability in the evening A topic , Often stay up late into the early morning 4 spot .

Two ： Tell me how I feel this week

Read this book , The harvest is still quite deep , Some have learned , Or something that I think is very simple , The actual operation is not simple , such as C++ Of string,string I have learned this since winter vacation , Later, I read the algorithm notes and so on , Until now, I suddenly have a feeling of enlightenment , Only then discovered string, Far so powerful , I can do many things that I didn't think of before , At the same time, I also feel the importance of doing questions , If you don't do questions , You can't realize how to use a knowledge point , Not online OJ Of WA, I don't know how to write questions , Did you write it yourself , No improvement .

3、 ... and ： Talk about the harvest

Do things bit by bit , The reason why I plan to go back to the Olympiad of Informatics , Because I'm doing USACO Many problems have been found in the process of , It's not that I don't understand , I don't know how to deal with the data when I see it . And in simple questions , You will also encounter this problem , I personally think , Or less code experience , Not enough . It's two different things to know whether learning and living can be used , If you lack code experience , Maybe you will know everything in the end , Nothing will come true .
