How do I implement a Fibonacci heap in Python?

How do I implement a Fibonacci heap in Python?

To implement a Fibonacci heap, start by defining the node structure with properties like key, degree, and child pointers.

What operations should I include in my Fibonacci heap implementation?

You should include operations like insert, minimum, extract-min, union, decrease-key, and delete.

Can you explain the decrease-key operation?

The decrease-key operation reduces the key of a node and, if necessary, cuts it from its parent and adds it to the root list.

What are the advantages of using a Fibonacci heap?

Fibonacci heaps have better amortized time complexities for operations like decrease-key and merge compared to binary heaps.
