WebThis relation is just a set of pairs, where the first element of each pair is from A, and the second element is from P. Another relation would be { ( yi, 19), ( yi, 20), ( yi, 18) }; there is no requirement that all values from A or P be present. Relations turn out to be a very powerful way of thinking about computation.

WebQuestion #6: Remove every other element (30 points) Write a Prolog predicate remove_every_other(X,Y) that is true if list Y is just list X with every other element removed (the two lists should have the same first element).

WebFrom our second example, [mia,robber(honey_bunny),X,2,mia], we learn that all sorts of Prolog objects can be elements of a list. The first element of this list is mia, an atom; the second element is robber(honey_bunny), a complex term; the third element is X, a variable; the fourth element is 2, a number. chanthol khleang
