When data contains more than numbers: > item_list = > heap = makefheap() > for item in item_list. > fheapunion(heap1, heap2) > getfheapmin(heap1) -1 > sorted_list = > while heap1.num_nodes. Using mergable-heap operations: > from fibheap import * > heap1 = makefheap() > heap2 = makefheap() > num_list1 = > num_list2 = > for num in num_list1. Installing using pip: > pip install fibheap Remove x from the heap by first setting its key to minus infinity and extracting the heap’s min. This procedure simply concatenates the two root lists. This procedure moves each of the minimum node’s children to the root list, removes the minimum node itself from the root list, and consolidates the resulted tree to reduces the number of trees. The number of trees of a Fibonacci heap is always the number of roots. The roots of these trees are doubly linked and form a circular loop as in the case with siblings. A Fibonacci heap can contain many trees of min-ordered heap. min: points to the node that contains the minimum key.A node becomes unmarked whenever it is made the child of another node. mark: (description by Cormen et al.) is either True or False, indicating whether the node has lost a child since the last time it was made the child of another node.degree: the number of the node’s children.To access all the children of the node, first access the representative child, then access all the representative child’s siblings through left and right attributes child: the representative child of the node. If x is an only child, it is its own left and right sibling. The node and its siblings are doubly linked, so they form a circular loop. left, right: the node’s adjacent siblings.The data structure also supports key-decrease and delete, although using these two operations requires users to create nodes for items themselves. (chapter 19) Fibonacci heap supports mergeable-heap operations, including make-heap, insert, minimum, extract-min, and union. To solve this problem I got inspired by a similar question here in Stackoverflow Single Statement Fibonacci, and I got this single line function that can output a list of fibonacci sequence. The data structure and its operations are described Cormen et al.
