Data Structures and Algorithms Full Course with Interview Q & A | DS Algo Interview Questions Solved

🔹 What is Data Structure and Algorithm?

Data Structure can be referred to as a collection of data objects that allows storing, organizing, and retrieving data on systems. An algorithm refers to a set of steps used in completing a certain task or to get the desired output. A deep understanding of Data Structures and algorithms helps in efficient and well-optimised coding.

Data Structures and Algorithms are important since they are often considered to be the root or the foundation of computer science. They play an important role in implementing software and at the same time in the job interview process as well.

🔹 Coding Interviews at FAANG. Are They Tough to Crack?

Short answer. Yes. Every year, FAANG tops the list of the most sought-after companies for programmers around the globe. The salary packages, the working environment, and additional perks are few reasons why coders want to ace the interview of these companies.

We analyse the important questions and provide step by step solutions for in-depth understanding.

Types of Data Structures
There are two types of data structures:
Linear data structure: If the elements of a data structure result in a sequence or a linear list then it is called a linear data structure. Example: Arrays, Linked List, Stacks, Queues etc.

Non-linear data structure: If the elements of data structure result in a way that traversal of nodes is not done in a sequential manner, then it is a non-linear data structure. Example: Trees, Graphs etc.

Insertion sort doesn't have any log. It's n times to run over the array and each iteration has an increased number of swaps by one. It's sum of series: 1+2+3+...n-1 which is n(n-1)/2= o(n^2)

[arunchaurasiya]

Sir data structures interview questions again to again new question available video create

[nerd]

I was thinking to enroll for Advanced DSA but i had a doubt that will u be teaching mathematics or do we need to already know it ?

[Manojsingh-cpeq]

I am not good in english so i am not able to learn properly sir
