Web2 days ago · 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 … Webfrom bisect import bisect_left, bisect_right class SortedCollection(object): '''Sequence sorted by a key function.
