Data Structures & Algorithms, Level-up for Coding Interviews (Udemy.com)

First of all, this course is advertised to be "for coding interviews" but it uses too old-fashioned c++ to be useful. For example, widespread use of NULL instead of nullptr, very old fashioned arrays, no use of initialiser lists, constant use of raw pointers (nowadays during a real-life interviews it makes a very bad impression !) etc. Apart from that, explanations of algorithms are often chaotic and difficult to follow - instead of professional animations or drawings the author just scribbles notes by hand during a lecture, which makes them more and more difficult to decipher as algorithms get more complicated, sometimes he just scribbles literally over his own notes and it becomes very hard to read at all. The use of single-character variable names against any clean-code convetions doesn't help either. English is also far from perfect, which may be ok for a developer, but not for a professional lecturer with paid courses, and combined with background noises makes it difficult to concentrate on a problem itself. Overall, you have a lot of exercises gathered in one place if you want to practice, but you may often find it is actually easier to read such pages as geeksforgeeks or other free online resources (!) than to understand explanations in this course, even free online resources often have much clearer diagrams and drawings (!) and paid courses even have professional animations while at times you really have to struggle here to get what the author had in mind.

I used to have a hard time coming up with solutions on my own while solving problems online, I wasn't able to think in right direction, as to which data structure to use and what approach to follow! But having completed this course more than half, I must say that now itself when a new problem comes in front of me, my approach and thought process now much better aligns with expected solution! All thanks to Prateek Bhaiyya and coding minutes, for curating such a fine selection of problems so that it covers most important concepts and opens up our brain to thousands of more such problem!

To the point, nice question selection, great explanation. Very good course. Also a beginner friendly, though some basic knowledge of c++ is assumed and basic algorithm are briefed over, however they are mentioned anyways, so in case you don't know one can go and search. Overall a great course.

I am glad that my friend introduced me to this course. Learnt how to use which data structure in what kind of problems and got confident at solving Coding Problems. The explanation is simple and very easy to understand. The best part is, the course is kind of interactive. So, you can think about the solution/code after you get an idea or jist of a problem statement. Would recommend this course to anyone who has difficulty in understanding data structures and algorithms. Thanks Prateek.

Very good course, one thing about this course which I found very good is on the point explanation and questions as I already have some experience in coding so I want a course which tells me directly advanced thing(like I don't want how stack are used and all). This course perfectly suits me. Thank you. Looking forward to completing this asap.

One of the really top best course, I started my DSA Journey in March 2020 by following Prateek Bhaiya's DSA videos and bought this course for my revision and it really helped me a lot to excel on other platforms - GFG, LC, CC, CF. I highly recommend this course and do practice side by side the questions which videos has. Thanks once again to Prateek Bhaiya for this amazing pocket friendly course.

If you want to ace data-structures and algorithms, definitely you should take this course. I am impressed with the teaching style of sir, learned so many things that are helpful for me to get better at competitive programming. I really searched for this type course when i am getting started with CP, even though i know the basic of DSA, i am unable to solve the problems, but this course really made me to get better in CP. Thank you, respected instructor Prateek Narang, and entire team.

First of all I would like to say Thank you prateek bhaiya... Dil se shukriya bhaiya apka... Apne aise pandemic situation m ham sab learners k liye itne kam cost m itna accha content provid karaya ...... Well structured course material . I think every student who want to learn something better should join this course. Bhaiya please keep providing these type of courses especially Competitive programming . Thankyou

This is amazing course as The main idea behind this course is to focus on problem solving which is missing in many other online courses.If you are good at any programming language and basic data structures not algorithms then you are good to go with this priceless course. Thank you so much sir for this amazing course.

I am an intermediate level programming enthusiast. I have been practicing data structures an algorithms since an year and have acquired resources from here and there to study DSA and improve problem solving. However I had never come across such quality content as in this course by Prateek Bhaiya. This is a masterpiece and if you are one who wants to level up your programming and problem solving skills. I would highly recommend this course to you. Thank you again Bhaiya for this quality content.
