How to prepare yourself before appearing for data structures and algorithms interview

Posted on by Imarticus Learning

The method of organising data using a virtual system is called a data structure. The tables of data, or sequences of numbers, are all well-defined structures. An algorithm is basically a series of steps that are carried out by a computer, which takes input and then transforms that into target outputs.

The combination of data structures and algorithms helps programmers to build the computer programs of their choice. A highly optimised and efficient code can be ensured only by having deep knowledge of data structures and algorithms. If one wants to learn data structures and algorithms, there are solid courses available online.

Preparations for a Data Structure and Algorithms Interview

Full Stack Developer Course

For developing the skills that are required for acing a data structure and algorithms interview, it is very important to explore all the directions, ask the right kind of questions, and understand the most suitable practices along with common pitfalls of the modern software symptoms.

The main purpose of a data structure and algorithms interview is to exhibit one’s ability in order to become an appropriate engineering teammate by identifying strong coding, problem-solving and communication skills. Some of the things that one should focus on throughout the interview are:

  • Preparing Before the Interview

It is very important to have deep knowledge and talk about different kinds of data structures and all their weaknesses, strengths and how they can be compared to each other. It is better to execute data structures from scratch because that makes one more prepared for these interviews, compared to studying those data structures like an abstract concept. It is extremely important to be familiar with all the major algorithms. 

  • Understanding a Problem

Generally, the interview starts by briefly discussing a problem that the interviewee needs to solve. Many applicants start to code when they see the questions, but later on, that may often lead to errors. Instead, it is much more important to read the question thoroughly and understand the constraints. It is very important for the interviewer to get a good insight into the way the applicant thinks through a problem or an issue. It is very important to make the interviewer understand that the applicant is spending time on implementing the solution. It is also important to have enough time for coding the solution as well.

  • Conversing Through the Brute Force Solution

It is very important to talk through the brute force solution that the applicant can think of with the interviewer. Quite often, applicants skip conversing through the brute force solution because they think that the brute force solution is very obvious. This is actually a mistake. Even if it takes a lot of time, it is very important to come up with a solution to the stated problem. After talking through the brute force solution, it is important to ask the interviewer if they would like the applicant to implement that solution, or come up with a better solution.

  • Optimising the Solution

After talking through the brute force solution, the interviewer might ask for a better solution. If something like this happens, then it is very important to discuss the applicant’s approach with the interviewer and then understand what to optimise, space, time, or both. Some initial assumptions can change too while optimising. For that reason, it is important to check with the interviewer. Once the interviewer and the applicant agree on a specific solution, the coding starts. 

  • Coding the Solution

It is very important to make the interviewer understand what the applicant is doing. While coding, it is important to converse on the section of the code that the applicant is going to implement on a higher level and why it was written. The interviewer should understand the applicant’s code and whether that code would return the expected results and be a solution to the problem. There is a high chance of missing out on a bug or having a syntax error, and for that reason, it is necessary to go through the code thoroughly.

  • Testing the Solution

Debugging is an extremely important skill. If the code has any bug, the applicant can showcase his or her ability to analyse why the code failed and then fix it. Good programmers are more likely to solve bugs as they code, rather than writing a perfect code on their first attempt. It is very important to do some manual testing to make sure it performs the way the applicant expected it to work. 

  • Practising and Learning New Tactics

Practicing questions on data structures and algorithms is one of the most important ways of improving an applicant’s performance. Mostly, data structures and algorithms interviews are very similar and for that reason, practicing more means having a higher chance of facing problems that the applicant is already familiar with. One of the best ways to prepare for these interviews is by doing mock interviews. 

Conclusion

The full stack web development course from Imarticus helps the applicant to have a deep knowledge of web development technologies as well as data structures and algorithms. The full stack developer certification can help the applicants to acquire the knowledge needed to crack data structures and algorithms interviews.

5 SQL Tricks Every Data Scientist Must Know

The world of data science is changing the way we work, communicate, and live. Data scientists are at the forefront of this change, helping unlock new insights and improve our lives. But in order to do so, they need to understand SQL—the standard language for managing data in relational databases. 

Data science courses offered by Imarticus learning include SQL, Data Visualization with Power BI, Python, and many others. Let us look at the tips and tricks to get you to speed up.

  1. Use wildcard characters for ranges of values

If you want to find all the numbers between 1 and 10—for example—you can just type “1-10” into your query and get results instantly. You can also use “*” as a wildcard character for any value (e.g., “*a?” would return results with aaaa or aaa).

  1. Use LIKE and WITH to find specific patterns in strings

If you’re looking for a particular pattern within a string—like if someone’s name is “John Smith”—you can use LIKE to find those exact characters in your query: WHERE FIRST_NAME = ‘John’ AND LAST_NAME = ‘Smith’.

Use the LIKE operator to find all rows that match a pattern of characters or numbers. For example, if you want to find all the customers whose names start with “J,” use “Name” LIKE ‘J%’.

WITH statement. The WITH statement allows you to define a temporary table for your query so that you can use the results without repeating yourself.

For example, imagine you have data on all the colleges in the US that’s stored in one table called “college,” and they’re all represented by their state abbreviation (e.g., “WA” is Washington). Let’s say you want to know what percentage of incoming freshmen at each college paid full tuition (the answer will probably be 100%). You could try writing this query:

SELECT CAST(cnty AS FLOAT) AS percent_full_tuition FROM college

But you’ll get an error because CAST() only works with numbers. Instead, you can wrap up our query in a WITH statement like:

WITH college_data AS ( SELECT CAST(cnty AS FLOAT) AS percent_full_tuition FROM college )

  1. Sorting data

Data sorting is a key process in the data analysis process. It allows you to put your data into a specific order to easily find and analyze the information you need. One of the most basic ways to sort data is using an ORDER BY clause.

In SQL, you can use the ORDER BY clause to sort your query results according to any column or columns present in your query. To do this, simply add an ORDER BY clause that specifies how you want your query results sorted:

SELECT * FROM tbl_name ORDER BY col1 ASC;

This will sort your results by column col1 in ascending order (A-Z). If we wanted it sorted in descending order (Z-A), we would use DESC instead:

SELECT * FROM tbl_name ORDER BY col1 DESC;

The above query would return all records from table tbl_name with col1 values first, then col2 values, etc., until all records have been returned and displayed on the screen.

  1. Using Arrays

Each value within an array has its own unique index number that determines its position with other values within the array.

For example, if we had an array containing three values: John Doe, Jane Smith, and Joe Brown—and each value had its own index number (1, 2, 3), then our array would look like this: [John Doe] [Jane Smith] [Joe Brown].

The advantage of using arrays over traditional data structures, such as strings or objects, is that arrays allow you to store multiple values together without worrying about their order or relationship with one another. 

Arrays are a common data structure in SQL. An array is a collection of items with the same type and share the same name but may have different values. Arrays are useful because they allow you to store related information together without having to create separate tables for each item or value.

You can manipulate arrays in many ways using SQL syntax, including accessing elements within an array using subscripts or using functions that operate on an entire array (like SUM()).

  1. Derived table

A derived table lets you pull out just the parts of your query that are interesting to you, without worrying about what else might be in there. For example, say you have a bunch of users’ names and their favorite colors:

SELECT name FROM users_table WHERE age > 18;

This query would give us a whole list of users’ names, but we don’t really care about the rest—we just want to know what people like as their favorite color! We could do this with another query:

SELECT name FROM users_table WHERE age > 18;

SELECT favorite_color FROM users_table WHERE age > 18;

This would give us back just one column instead of two (which is why it’s called a “derived” table).
