top-down reheapify
Top-down reheapify is a process used in heap data structures, specifically in binary heaps, to restore the heap property by comparing and swapping elements from the root down to the appropriate leaf position. It involves checking if the parent node violates the heap property with its children and making the necessary adjustments to maintain the correct order. This operation ensures that the largest (in a max heap) or smallest (in a min heap) element is at the root, which is vital for efficient heap operations.
