Weak heap

A **weak heap** is a data structure that is a variation of the traditional binary heap, designed to support efficient priority queue operations while allowing for a more flexible structure. It was introduced by David B. A. McAllister and R. G. Bartashnik in the context of efficient sorting and priority queue operations. ### Key Characteristics of Weak Heaps 1. **Structure**: A weak heap maintains a binary tree structure, similar to a regular binary heap.
