Test-series
A d-ary heap is like a binary heap, but instead of two children, nodes have d' children. A d-ary heap can be represented in a 1-dimensional array as follows. The root is kept in A[1], its d children are kept in order in A[2] through A[d + 1] their children are kept in ... 2] through A[d2 + d + 1] and so on. What index does maps the jth child for (1 ≤ j ≤ d) of the ith index node?
