Preface
Two days ago, a small partner told me that I finally spent three difficult months in Ali, and finally got back to normal. They have been studying for the past three months. They are afraid of being eliminated. It would be best if Huangtian pays off.
The friends also shared their study notes to the editor, let's learn together! ! !
The answer is at the end~~
notes
- How to achieve an efficient reverse output of a singly linked list?
- It is known that sqrt(2) is approximately equal to 1.414, and it is not required to use a math library. Please find sqrt(2) accurate to 10 digits after the decimal point

- An existing batch of emails needs to be sent to subscribing customers, and there is a cluster (the number of nodes in the cluster is variable and will dynamically expand and shrink) to be responsible for specific email sending tasks. How to make the system complete the sending as soon as possible?
- There are a number of meteorological observatories. Now it is necessary to obtain the observation data of these stations and store them in Hive. However, the Meteorological Bureau only provides api query, which can only query a single observation point at a time. So if you can easily and quickly get the data of all the observation points?

- How many simple MOV instructions can be executed per second on a modern processor, and what are the main influencing factors
- Please analyze the relationship between MaxCompute products and distributed technology, the current market status and development trends of big data computing platform products
- How do you understand the metadata management in the big data platform, what is the metadata collection management system, and what impact will it have on big data applications?
- You understand the technical system differences, development trends and technical bottlenecks of common big data platforms such as Alibaba and other big data platforms, and outline the two aspects of storage and computing
- In the cloud computing big data processing scenario, thousands of tasks are running every day, and each task needs to read and write IO
- Maximum frequency stack
- Given a linked list, delete the Nth node from the bottom of the linked list, and return the head node of the linked list
- If you are asked to design a universal system that supports second-level backup and recovery of various databases, how would you design
- If you were asked to design a data flow and processing system that supports the real-time flow of data between databases, NOSQL and big data, what issues would you consider? How to design?
- Given an integer array and an integer, return the indexes of the two arrays. The sum of the numbers pointed to by these two indexes is equal to the specified integer. Need the best algorithm, analyze the space and time complexity of the algorithm
- Please evaluate the execution result of the program?
- How to judge whether two linked lists intersect
- How does zk elect Leader?
- Distributed notification and coordination
- zk session mechanism
- zk configuration management service
- What are the application scenarios of zookeeper?
- zookeeper file system
- Four types of znodes for zookeeper
- zookeeper notification mechanism
- zk naming service
- zk cluster management
- zk's distributed lock
- zk queue management
- zk data replication
- How zab works in zk
- How does zk ensure the order consistency of things
- Server working status under zk cluster
- How does zk elect Leader?
- What is a replica set in MongoDB?
- What method can MongoDB use to format the output result?
- How to update data in MongoDB?
- Why use Object ID data type in MongoDB?
- What are the common performance problems of Redis? How to solve?
- There are 2000w data in MySQL, and only 20w data in redis. How to ensure that the data in redis is hot data
- The difference between stored procedures and triggers
- Four characteristics and meanings of database transactions
- Mysql primary key super key candidate key foreign key
- Database paradigm
- Types of Mysql connection
to sum up
Sure enough, there will be pressure in big factories, and the same will be motivated. If you don't make progress, you will be eliminated. The little partners share very practical technologies.
There are too many notes to write out, the editor will summarize the answers and the remaining notes!

The readers don’t pay attention, eh, I’m not panicking at all, he just let him go, talk to them first , oh, got sprayed, spray him? If it doesn't exist, I backhanded it and apologized to him sincerely, depending on what the reader said, eh, this is very comfortable. The comment area is going to blow up Not a big problem, I will have a per point a praise , Edge OB wave of how, said the comments area. Oh, this man, iron-headed baby, is very spiritual and seems to be really going to explode. My scalp is numb, but I am not afraid. At this time, I have to think backwards and give him a copy of learning materials for free . This wave is not bad, what do you think? Dignified and nice bloggers are afraid of your comment area? I'm in a good mood, I don't know anything
