The exact value of the above (the worst-case number of comparisons during the construction of d-ary heap) is known to be equal to:, where s d (n) is the sum of all digits of the standard base-d representation of n and e d (n) is the exponent of d in the factorization of n ... D-ary heap. D-ary heap is a complete d-ary tree filled in left to right manner, in which holds, that every parent node has a higher (or equal value) than all of its descendands. Heap respecting this ordering is called max-heap, because the node with the maximal value is on the top of the tree. Analogously min-heap is a heap, in which every ....
