WebHace 1 día · Source code: Lib/heapq.py. This module provides an implementation of the heap queue algorithm, also known as the priority queue algorithm. Heaps are binary trees for which every parent node has a value less than or equal to any of its children. This implementation uses arrays for which heap [k] <= heap [2*k+1] and heap [k] <= heap … WebI'm trying to count the number of comparisons and swaps in heapsort algorithm (num_comps and num_swaps accordingly): import numpy as np import timeit def heapify(arr, len_arr, i ...
