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 8 ай бұрын

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)

@JD797 Жыл 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

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