Why should I learn data structures and algorithms ?

Building Block for your Career

No matter whatever career path you choose in the field of computer science, data structures and algorithms lies at the root of it

Essential skill for Job in Software Development

All top product companies including FAANG will test your skills in data structures and algorithms.

How do you choose between C++ / Java / Python ?

C++

C++ programs are directly compiled into machine-executable codes which consumes less time to execute the code. Hence, it is widely used in competitive programming where you are expected to optimise time and memory. So, if you are interested to explore competitive programming then it is good to start with C++ language

Java

Java programs are easy to understand, structured and less prone to errors. Also, they are platform independent and portable which makes it a good choice for mobile, web and desktop applications. So, if you are looking for a career in software development then it is good to start with the Java language

Python

Python programs are simple in syntax with extensive library support which helps the programmers to come up with required logic with few lines of code. It is popular and widely used in the data domains like data science, Machine learning, deep learning etc.., So, if you are looking for a career in the field of Artificial Intelligence then it is good to start with the Python language

For you to get placed in a product based company you need …

I must say that taking this course was one of my best decision. I was struggling in the coding test during the internship period so I decided to go for this course during the 5th sem and that really helped me in polishing my skills. My tutor was Manisha Ma'am and she explained the topics very well. Overall It was a great learning experience.

I cleared the training in a month and was put into SAP ABAP, which I never liked. It was then when I decided to learn full stack web development since it appeared the most sought am ...
