The basics of coding fundamentals are not as difficult to understand once you have a clear understanding of the concepts.
And, what better way to learn these concepts than from the absolute best individual who is renowned for his coding skills and has worked with Google as a Software Developer in the past?
He’s none other than Raj Vikramaditya also known as Striver. This man has been widely popularised for creating the Striver Sheet for SDE preparation consisting of more than 180 questions at length.
These questions are compiled keeping major technical interviews in mind so that no aspirant feels left out while preparing to land their dream position in companies like Microsoft, Google, or Amazon.
It is quite intriguing how this online resource claims to prepare you for your next coding interview in the course of 2-3 months!
If you are interested in knowing how to let us walk you through everything that you need to know about the Strivers SDE Sheet.
How to learn using the Striver SDE Sheet?
Looking to sharpen your skills as a programmer by practicing Data Structures and Algorithms?
If yes, the Striver Sheet for Software Development is just the right resource for you!
Designed by a former Google Software Developer, Raj Vikramaditya (also known as Striver), this practice SDE Sheet has been specially crafted to make the users understand the key areas of Software Development.
From Google to Amazon, nearly all the multinational tech companies have been covered in the SDE Sheet so that you can put your best foot forward.
There are a total of 180 questions included in the Strivers Sheet covering all the important DSA questions that you will surely encounter in your interview.
Along with that, the SDE Sheet also allows you to track your progress and participate in discussions and offer your feedback to the other users of the sheet.
You can download the Striver SDE Sheet in PDF format from any of your web browsers or search engines.
Now, in order to start practicing, you need to have a clear understanding of the following:
- Concepts of Data Structures and Algorithms
- Object-Oriented Programming and its key areas
- Types of Data Structures in Programming
The types of problems that you can expect to find in the Strivers SDE Sheet are discussed in the following section.
List of problems on the Strivers SDE Sheet
From backtracking questions to Matrix zero problems, the Strivers SDE Sheet has divided coding sections into different categories in order to make them easier to locate.
Let us discuss these sections in detail.
Arrays
In the arrays section, you will find the following set of problems.
You can solve these problems by setting time limits for yourself and learning what sort of questions you might encounter in your technical interviews:
-
Setting matrix to zero problems
The set matrix zero problems require the programmer to set the values of each row and column to zero if any of the elements in the given matrix equals a zero.
-
Pascal’s Triangle
This problem statement requires you to recover the N oars in a given Pascal’s Triangle.
-
Next Permutation
In this problem statement, you will be given an order of numbers that are arranged lexicographically. You can required to rearrange these numbers from the given set of integers.
-
Kadane’s Algorithm
This problem requires you to find contiguous Subarrays that have the most significant sum.
-
Sorting an Array of 0’s, 1’s and 2’s
As the problem suggests, you will have to sort a given array for their 0’s, 1’s, and 2nd elements but without using the sorting algorithm directly.
-
Stock buying and selling
This problem is based on enhancing profits hence, you may have to decide the proper algorithms that will derive the maximum amount of profit for the given problem.
Linked List
- In the linked list-based problem, you will have to create a program where you can overturn a given linked list
- You might also be asked to return a specific node from the middle of a linked list
- There are also problems based on merging two different linked lists
- Finding the Nth node of a Linked List is also another common problem
- Other problems include adding two different numbers and returning the output as a Linked List
- Also, you might be asked to delete the nodes of a linked list
We hope that this might have added to your knowledge of the Striver Sheet. If you would like to discuss a few solved questions from the SDE Sheet then check out the following section.
How to answer questions on the Strivers SDE Sheet?
If you are interested in solving advanced-level coding problems from the SDE Sheet such as an array or backtracking questions, then you certainly need to have a clear understanding of the following concepts of coding:
-
Declaring Variables
Variables in programming are used for storing values and these values can be declared by allocating specific variable names to them.
The variables with underscores, digits, and letters can be easily defined. Variables can store data types such as Dictionary, Tuple, Lists, Strings, and Numbers.
-
Data Structures
These provide an efficient way for storing and retrieving data from memory. Some of the most commonly used data structures are Linked Lists, Queues, Stacks, and Arrays.
-
Object-Oriented Programming
This concept is based on objects and classes in programming data where the classes contain prototypes for generating objects in a computer program. The basics of Object-Oriented Programming that you need to learn about are Polymorphism, Inheritance, Abstraction, and Encapsulation.
Wrapping Up
The coding interview aspirants often have this question: is the Strivers SDE Sheet enough to practice for coding exams?
The answer would definitely be, yes. This tool has not only guided millions of applicants who aspire to crack their dream position at globally reputed tech companies but it also guarantees full preparation within the course of 2-3 months.
So, whether you are looking to sharpen your skills in solving Array-based problems or backtracking questions for that matter, the SDE Sheet by Striver is definitely your go-to solution!
