WebFeb 14, 2016 · 1 Answer. In your insert, percolateUp and percolateDown methods, you need to use getParent () and getChild () methods. Currently, insert method divides indexes by 2 to get to the parent of an element which is only true if you have a 2-heap. Also, your heap implementation uses array [0] as a placeholder. In that case, your getParent () and ... WebThe d-ary heap or d-heap is a priority queue data structure, a generalization of the binary heap in which the nodes have d children instead of 2.
