end of november summary
unexpected vacation
A few days ago, there have been gossip that it is going to be a holiday, and several schools in the surrounding areas have left. Then my school also notified that in the early stage, the school said that there is only one chance for CET-4 and CET-6, and those who want to take the exam can only stay in school. Therefore, many people want to stay in school to pass CET-4 and CET-6 before leaving. It can be seen that the school I still want students to stay in school. Now it's reversed, many people can't leave, the school has been urging them to leave, saying that the epidemic is very serious now, maybe they can't leave if they leave later, and they can't go home for the New Year. I'll just stay at school, and I'll leave when the school really urges me to leave.
Life
In terms of life this month, there is nothing special.
In the middle of the month, the group held an algorithm competition and only took the seventh place.
Then I still played from time to time at noon, and I felt that my golf skills had really improved.
The original plan was to finish the selection from one hundred to the algorithm, but only 80 of them were written, and I couldn't write the rest. I just wanted to start a review, and opened a binary search. I got a medal after finishing writing a few days ago, and I feel that I have a deeper understanding of binary search.
Oh, by the way, today I am trying to beat the weekly competition. When I wrote the third question, I found a problem. In js, if I use the shift method of the array, the time complexity is O(n), while the method of pop The time complexity is O(1), so it is better to use less queues and more stacks. Today I timed out when I used the queue, but there was no timeout when I used the stack.
The group recruiting has been going on quietly for a while, about ten people have been recruited, these days the student union has finished recruiting new students before letting the group publicize, the original group of more than 50 people has more than 100 people in a while.
I should be one of the first interviewees. One of the juniors I interviewed at the time was pretty good. I have learned a lot in private and have a strong thirst for knowledge. Learning attitude is very good. In the end, it was assigned to my group.
After looking at Jiwang and the basics of browsers, it feels very fun.
to develop
I encountered some problems in project development, because I had to write the interface myself, so I learned node.js+MySQL and SQL commands this week. I didn’t learn much, but I should be able to write some simple interfaces. . After I finish learning, I will write the interface, and then continue to develop the project.
