Question: The pseudocode in this assignment uses x : integer := Y to denote declaring a variable x, and binding it to the value Y. Writing

The pseudocode in this assignment uses x : integer := Y to denote declaring a variable x, and binding it to the value Y. Writing x := Y binds an existing variable x. print a, b should print the value of the variables a and b separated by a comma 1) Indicate the binding time for each of the following decisions in Prolog. Explain your answers: a) The total amount of space consumed by program code and data. b) The ":-" symbol. c) The name "descendant", as in the descendant relation defined in the class slides. d) The binding of X to y, when applying the rule reachable(X, Z) :- edge(X, Y), reachable(Y, Z). to the query: ?- reachable(y, w).
