WebJun 12, 2024 · 2 The number of items in a full d-heap of n levels is (1-d n. A little algebra tells us that the number of levels required to hold n items in a d-heap is log d (n*(d - 1) + 1). So a 4-heap with 21 items takes log 4 (20*(4 - 1)+1), or 2.96 levels. We can’t have a partial level, so we round up to 3. See my blog post, The d-ary heap, for more ...
WebMore generally for a generalized d-heap, the items may be viewed as the nodes in a complete d-ary tree, listed in breadth-first traversal order: the item at position 0 of the array (using zero-based numbering) forms the root of the tree, the items at positions 1 through d are its children, the next d 2 items are its grandchildren, etc.
