cracking the coding interview programming questions and solutions

The following are some of the problems that you might encounter in the programming process and the corresponding solutions: ** I. Difficulties and solutions in the introductory stage ** 1. ** Loss of motivation due to delayed feedback ** - ** Problem Description **: In the first month or two of learning programming, even if you invest time in learning, you will feel that you have not mastered much knowledge and skills, and the programming will not immediately give you obvious feedback. - ** Solution **: Perseverance is the key. You have to get through the three to six months entry period. The programming process was a gradual process. One should not expect huge results in the early stages. 2. ** Difficulty encountered during the introductory period ** - [Problem Description: Encounter a difficult problem during the introductory stage. Spend a lot of time studying it but still have no clue.] - ** Solution **: You can skip this problem temporarily. With the accumulation of knowledge, these problems might be easier to solve. 3. ** Lacking a clear learning goal ** - ** Problem Description **: Some people learn programming purely to pursue high-paying jobs. For example, they expect a monthly salary of 10,000 + from the beginning. This kind of utilitarian goal will make the learning process painful and easy to give up. - ** Solution **: Set a small project for yourself as a goal to learn programming. When he completed this small project and made a work, he would gain a sense of accomplishment. At the same time, he would basically have the ability to find a junior development position, and he would gradually advance in the future. ** II. Knowledge and Skill Problems in Learning and Their Solution ** 1. ** Learn a programming language ** - [Problem Description: I don't know how to learn a programming language systematically.] - ** Solution **: - First, he learned the basic grammar, including data types, operators, branches and cycles, arrays, functions, hashes, and so on. - Then, he used the language to implement basic data structures, such as sequence table, linked list, stack, queue, string, tree, binary-tree, BST, graph concept, adjacent matrix, adjacent table, etc., and he had to be able to write his own code to implement it. - Then, he would use the programming language to do some basic algorithm questions, such as enum, sorting, simulation, greed, dichotomous enum, prefix-sum, double-pointer, deep search, wide search, dynamic programming, etc., to improve his programming thinking and problem solving skills. - Finally, he would do a practical project. It could be a game, a web page, or other software. For those who had no direction and no programming foundation, they could choose Python first. If they were more confident, they could choose C/C++. 2. ** The lack of programming ability in the field of network security (for network security studies)** - ** Problem Description **: In the field of network security, when you advance from a "script kid" to a real network security engineer, you lack programming skills. When faced with complex situations in actual penetration testing, you are unable to extend existing tools or write tools and automated scripts that meet the requirements. - ** Solution **: Students who have zero basics can choose one of the script languages Python, Python, Go, or Java, learn programming from common libraries, build a corresponding development environment, and choose a suitable IDE (for example, you can choose Wamp and XampP for the Python environment, and I strongly recommend Subli as an IDE). 3. ** Solve specific programming challenges ** - ** Problem Description **: You will encounter various challenging problems on platforms such as HackerRank, LeetCode, Project Leonard, Coderbyte, etc. during your programming practice or work, such as "sum of two numbers","product of the largest palindromic string", etc. - ** Solution **: Use different solutions for different difficulty levels. For relatively simple warm-up problems such as "addition" and "addition", they could construct solutions from simple logic. For "easy" problems such as "sum of two numbers", they could use simple brute force methods to solve them. At the same time, he could refer to the experiences shared by his predecessors on the Internet and use StackOverFlow, Quora, Google, and other resources to obtain solutions to related problems. ** 3. Data processing programming problems and solutions (such as cross-library access)** 1. ** Problem Description **: In data processing work, for example, when a data analyst performs cross-database data fetching, if he uses a regular report tool (such as FineReport) that does not support cross-database data fetching, he will face the problems of complex code logic, difficult maintenance, and low operation efficiency when writing complex codes (such as SQL statements) to extract data from different database, clean, convert, and associate analysis. 2. ** Solution **: You can use low-code ATL tools (such as FineDatalink) to replace tedious code writing through a visual operation interface. It is as easy as building blocks to complete data processing tasks, such as cross-database data association, column transfer, data cleaning, and other operations. You can also use Spark SQL, Python, and other operators. "When a programmer meets a psychologist" is equally exciting. Everyone is welcome to click to read it!

Ren'Py is a great choice. It's specifically designed for creating visual novels and has a lot of built - in features for handling things like dialogue, character sprites, and scene transitions. Another option is TyranoBuilder. It has a user - friendly interface and is good for beginners. Python can also be used, especially if you want more flexibility and control over the coding process. You can build a visual novel from scratch using Python libraries.

Ren'Py is a great choice. It's specifically designed for creating visual novels, with a lot of built - in functions for handling things like dialogue, character sprites, and scene transitions. Another option could be Python with some additional libraries. Python is very versatile and can be used to build the logic for a visual novel if you're willing to put in the extra work to handle the visual and interactive parts.

The interviewer asked five questions: 1. What is the specific work content of the interview profession? What professional skills and knowledge are needed during the interview? What is the working environment and pressure of the interview profession? 4. What is the salary of the interview profession? 5. What are the common challenges and difficulties of the interview profession?

Ren'Py is a great choice. It's specifically designed for creating visual novels. It has an easy - to - understand syntax and lots of built - in functions for handling things like character dialogues, choices, and scene transitions. Another option is Twine, which is more of a text - based tool. It doesn't require much in the way of traditional programming knowledge. You can create interactive stories using a simple markup language. And Python can also be used, especially if you want to build a more customized visual novel system from scratch. But it might be a bit more challenging for complete beginners compared to Ren'Py or Twine.

One horror story is when the interviewer was constantly interrupting the candidate. The candidate was trying to explain their solution to a coding problem, but the interviewer kept cutting in with their own thoughts, not letting the candidate fully express themselves. This made the candidate very nervous and they couldn't perform at their best.

There were a few points to note during the director's interview: Familiar with film history and film theory: Understand the history and development of film, master the basic theories and concepts of film, and be able to explain the content of film history and film theory. Familiar with film genre and techniques: Understand various film genre and techniques such as comedy, action, romance, science fiction, etc. and be able to choose suitable film genre and techniques for different interview scenes. 3. Storytelling ability: During the interview, you need to be able to clearly tell the story, including the background, plot, characters, etc. At the same time, pay attention to the fluency and expressiveness of the language. Familiar with the professional characteristics of directors and screenwriters: Understand the professional characteristics of directors and screenwriters, such as the responsibilities and work processes of directors, the creative process and characteristics of screenwriters, etc. Familiar with the basic process of film production: Understand the basic process of film production, including shooting, editing, special effects, sound effects, etc., and be able to explain the basic steps and precautions of film production. 6. Possess certain acting skills: During the interview, you need to be able to perform confidently and truthfully, and be able to choose the appropriate way to perform according to the interview scene. 7. Teamwork skills: The directing profession usually requires teamwork to complete the project, so it requires good teamwork and communication skills. These are the things that you need to pay attention to during the director interview. I hope it will be helpful.

Some common ones include questions about leadership style, team management experience, and problem-solving skills.

One common type is the unprepared interviewer. They might not have a clear understanding of the skills they are supposed to test, so they ask irrelevant questions or misinterpret the candidate's answers. Another is the overly strict time limit. For example, being given a very complex problem but only a few minutes to solve it. It doesn't give the candidate enough time to think and code properly.
