WebJun 4, 2012 · Heapsort is a good sorting algorithm because it's O (n log n) and it's in-place. However, when you have a linked list heapsort is no longer O (n log n) because it relies on random access to the array, which you do not have in a linked list. So you either lose your in-place attribute (by needing to define a tree-like structure is O (n) space). WebFeb 8, 2024 · You can use heap.pop () to pop the first element in the heap, and heap.sort (key=lambda x: x.f, reverse=True) to sort it based on the values of the attributes.
