Question: Given the internal Bayesian network structure N, implement a d-separation oracle which, for any three sets of nodes input to it, X, Y, and Z,

Given the internal Bayesian network structure N, implement a d-separation oracle which, for any three sets of nodes input to it, X, Y, and Z, returns:

???? true if ???? ???? (i.e., Z d-separates X and Y in N);

???? false if ???????? ???? (i.e., Z does not d-separate X and Y in N);

???? some diagnostic (a value other than true or false) if an error in N is encountered.
