Helper Utilities

Core types

• Ordering: enum with LT, EQ, GT used across comparators.
• Comparator<T>: (a, b) => Ordering signature accepted by every collection.
• Node<T>: linked-node structure used by linked lists/queues/stacks.
• ICollection<T>: base interface implemented by all structures (add, remove, iterator, reverseIterator, size, comparator).

printHeap

Utility for visualizing Fibonacci heap levels in the console.

const heap = new FibonacciHeap(createComparator('priority'))
heap.insert({ priority: 1 })
printHeap(heap)

It traverses neighbours/children and prints each level with parent references, making it easier to debug heap unions or decrease-key operations.

Keep these helpers in mind when integrating the collections with custom tooling or diagnostics.
