WebHow would you represent a d-ary heap in an array? Answer this question by: Giving an expression for J-th-Child (i,j): the index of the j-th child as a function of the index i of the given node, and the child index j within the given node. The 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. Thus, a binary heap is a 2-heap, and a ternary heap is a 3-heap. According to Tarjan and Jensen et al., d-ary heaps were invented by Donald B. Johnson in 1975.

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 ... dailymotion sliders
