Project description


Existing heapq library can be used as a maxheap by negating the values passed We need to negate back while retrieving from the heap as well. This can result in a cumbersome interface.

Maxpheap is a implementation similar to heapq that lets you push and pop to the heap. In a maxheap largest element has the priority.

>>> import maxheap


heap = []            # creates an empty heap
heappush(heap, item) # pushes a new item on the heap
item = heappop(heap) # pops the largest item from the heap
item = heap[0]       # largest item on the heap without popping it
heapify(x)           # transforms list into a max heap, in-place, in linear time
item = heapreplace(heap, item) # pops and returns largest item, and adds
                               # new item; the heap size is unchanged
