10 rooms, numbered 1 to 10, need to be rewired, but there are constraints on the order in which this can get done. Rooms 5 and 8 must be rewired before starting on 6 Room 1 must be rewired rewired before starting on 7 and 9 Rooms 4 and 5 must be rewired before starting on 2 Rooms 8 and ... -8-5-6 and 3-1-7-10-8-5-2 each of length 7." <--quoted from answer How is it done?How is it connected to DAG?

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 order in A[d + 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?

Let a decision problem $X$ be defined as follows: $X$: Given a Turing machine $M$ over $\Sigma$ and any word $w \in \Sigma$, does $M$ loop forever on $w$? You may assume that the halting problem of Turing machine is undecidable but partially decidable. Show that $X$ is undecidable Show that $X$ is not even partially decidable
