In fact, after working for 2~3 years, you will find that with the deepening of the work, the problems encountered in the work will become larger and the amount of data processed will also become larger.
At first, I may work overtime patiently and wait for the machine to finish processing before going home, but in the end, it is usually late at night to finish processing these data.
Faced with such a problem, it can actually be solved by data structure. Carefully combing the problems encountered in development, you will find many problems in your work, which can be solved with simple logic.
Like what you are familiar with. How to count 99% response time of business interface in real time?
You may first think that every query, all the response times will be sorted from small to large. If there are 1200 data in total, then 1 188 data will have a response time of 99%.
Obviously, it is very inefficient to sort every time you use this method to query.
However, if we know the data structure of heap, two heaps can solve this problem very effectively.
So data structure is a sharp weapon for our programmers to improve efficiency!
In addition, if you have worked for 2 to 3 years, you may want to jump ship and join a big factory.
But when you go to an interview, you often come across the topic of data structure and algorithm.
At present, data structure and algorithm are necessary questions for interviews in many well-known enterprises.
During the interview, major Internet companies at home and abroad have heard some topics about data structures and algorithms.
Moreover, the bigger the company, the more attention it pays to data structures and algorithms.
For example, from June 2065438 to June 2009, the data structure topics involved in Ali's interview were:
20 19 Data Structure Topics Involved in Huawei Interview:
At present, many interview questions of small and medium-sized enterprises involve the knowledge of data structure.
In fact, you will find that even large and small companies will find it more and more difficult to interview in order to screen better talents.
Therefore, data structure is an important threshold to enter a large factory.
In short, if you want to improve your work efficiency and enter a larger company, data structures and algorithms are a hurdle you must cross.
From Yichuan Media, AsiaInfo, Open Education, Programmer to Architect, and then to Teacher Fan, the technical manager, we have laid a good foundation for the data structure through various working methods in the past six years, combing a lot of experience and doing in-depth thinking in the process.
Work hard with Teacher Fan for the data structure, skip the code trap, complete the data structure clearance as soon as possible, and have a greater chance of promotion.

How does the teacher explain this course? #
The teacher introduced the boring and abstract structural rules and mapped them into the actual project in detail. Then try to break away from the complex mathematical foundation and map the relevant theories to many common applications, so as to lower the understanding threshold of learners and enable them to learn even if they have no foundation.
At the same time, the course covers at least 50% interview questions about data structure in common Internet companies. Sequence and stack are basic topics, and tree is a relatively advanced topic. Understanding and grasping can give full play to interview confidence. Walk up a flight of stairs
# Course introduction #
# What can I get? #
1 to improve the efficiency and quality of programming.
Familiar with the principle of data structure, don't worry about the principle of requirement realization for complex projects.
2. Improvement of optimization ability
With the deepening of understanding, we can find the code that is contrary to the characteristics of data structure in our work and have the ability to optimize and modify it.
3. Improve the interview success rate.
Learn more than 50% of Internet companies' data structure interview questions, and improve the interview qualification rate.
# User group #
