  • 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.

    • 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

  • 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)

    @user-ln7ek5zn2j@user-ln7ek5zn2j10 ай бұрын

    • 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

  • "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.

    • 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.
