[@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

[@iAPX432]

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

[@Omar_Al_Seddik]

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

"Algorithms + Data Structures = Programs" was a 1976 book by Wirth, the designer of the Pascal programming language. Algorithms were all the rage in computing 50 years ago. Train yards and queuing in the 1960's, sorting, traversal and scheduling in the 1970's for Operations Research, an entire field that shortly disappeared. Then the focus turned to symbolic processing and other problems because algorithms were largely solved and available by calling libraries. While worthy of study for students, algorithms as questions in interviews for professional jobs shows a complete misunderstanding of solving real world problems and what a healthy code base should look like.

[@feroast1]

I'm always surprised when an interviewer doesn't follow with questions on how I'd implement in production code since, as you point out, most langauges have optimized solutions for us to leverage. However... DS-Algo challenges are the best way to determine candidate understanding of the computer science behind implementation choices. It's the best way to differentiate real coders from script-kiddies.

[@Shazam999]

@@feroast1My first developer question is always "has any of your code made into a production environment?" Most people actually answer no. I have no idea what people do all day.

So you gave 127 interviews. So you were the interviewer. And the interviewee were asking about algorithms so much that you were able to come up with 5 tops algorithms.

[@iirekm]

The problem is that most coding interviews are unrealistic. The reality is that in 99% of programming jobs, you'll never write a complex algorithm, all you need is to know 1) what library / tool / framework use in what situation, 2) communication skills. Low-level coding skills are for most IT jobs unimportant. Also in 99.99% of programming jobs you don't have such small hard time limit constraints (e.g. 1 hour to solve problem), but you rather can work for days (at least) and can use Google, StackOverflow, or help of colleagues. I reject job ads when they even mention that there will be a coding task. Coding interviews make sense only for maybe 1% of IT jobs where writing low-level middleware is involved (database storage engines, cryptography libraries, compression libraries, graphics libraries, ML libraries, etc). For most programming positions system design interview (e.g. what framework / library / technique would you use and why) is a much better option, sadly still few companies do it, still requiring nonsense coding interviews.

For the "Top k elements" for your solution the complexity is actually O(nlogn), since in worst case scenario k tends to n.

[@aliiucer]

no it can never exceed nlogk, assume k==1 so there is no way to make it nlogn

[@muditjaiswal]

@@aliiucer you are considering the best case scenario, mostly folks talk about worst case complexity & average case complexity when talking about an algorithm.
