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 [2*k+2] … Ver más A heapsort can be implemented by pushing all values onto a heap and then popping off the smallest values one at a time: This is similar to sorted(iterable), but unlike sorted(), this implementation is not stable. Another … Ver más Various structures for implementing schedulers have been extensively studied, and heaps are good for this, as they are reasonably speedy, the speed is almost constant, and the … Ver más The remaining challenges revolve around finding a pending task and making changes to its priority or removing it entirely.
