I gave 127 interviews. Top 5 Algorithms they asked me.

1. How to learn Data Structures and Algorithms?
2. The best course to learn Data Structures and Algorithms in Java and Python
3. How to crack coding interview?
4. How to use Leetcode effectively?
I will answer all these questions in this video.

I like how you explain simply with a very calm voice things that might seems complex at first! Great work!

This is great work. Please continue giving info about interviews, so that I can train my students better.

Sahil, amazing Video. Loved the way you explained the problem with an animation. Highly recommend you launching a course in DSA using Python with similar explanation 🙏

[@zedddoctor]

Your videos are so helpful, I inevitably end up saving them in a playlist so I can refer to them later whenever I need guidance. Thank you so much.

I like how you explain recursion - I always draw a stack and dive into each step but that's just cost a lot of time. And 127 interviews is just impressive! Keep up the good work power couple! 🙌💪

Very good explication. There are algorithms here I've never heard of or for that matter never had any use for in my developer career but it's nice to broading your knowledge of things. Thank you for sharing.

[@davit_code8929]

If you don't need to return the elements in order, Top k elements can be optimised even further with quickselect to Time complexity of O(n + k) => O(n) AND bringing down the space complexity to O(1) too. Quickselect has a worse time complexity of O(n^2), but picking the pivot randomly each time gives O(n). The chances of always picking a bad pivot that would make it O(n^2) with a random pivot is so small, that papers assume it never happens.

[@tho_norlha]

Just a question: You can do one for loop to get the largest let -> n Another one to remove that won’t -> n Repeat it 2 times so we get too 3 elts ->O(5n) = O(n) Am I correct ? If it’s too 3 elts, but I see that a heap might be better if we want the top k elts and if K is very large

[@AdnanDev-su5no]

I was taught all these in university, but never told how, why or where they are used. I have started to use these in my personal projects after watching your video. Thanks a bunch for spreading this valuable knowledge. And of course I do plan to use this info for coding interviews in the future apart from my projects 😅

[@user-ln7ek5zn2j]

For k largest/smallest elements we can do heapify which works in O(n) and then take k element in constant time. Second option is counting sort which works in O(n +k)

[@JD797]

Even with heapify in linear time, taking k elements is still klogk since when the top element is removed, the heap moves the last element to the top to replace it and sifts down, which is log k operation

[@Seeking_Solace]

We can solve it in O(n) time using bucket sort.

IIt's impressive to hear about your experience with 127 interviews and the algorithms they focused on. However, I'm curious about the circumstances that led to such a high number of interviews. Do you think there are specific factors or challenges that contributed to this? It would be really insightful to hear your thoughts on how to efficiently navigate the job market, especially for those who might find themselves in a similar situation.

[@grebmann]

127 interview to get a job ... that's what i call "Try hard". Well done man, never give up ;) Anyway nowadays, people just need to learn the algorithms and train on it for the interview. Everything that matter is the "Interview Skills". I saw a lot of indians going to the big tech companies by only mastering the art of interview but with poor business understanding and mediocre software engineering skills.
