1. Assuming the parent relation as defined in the following piece of Prolog code, what will be Prolog's answers to the following questions?
parent (pam, bob).
parent (tom, bob).
parent (tom, liz).
parent (bob, ann).
parent (bob, pat).
parent (pat, jim).
a) ?- parent (jim, x).
b) ?- parent (X, jim).
c) ?- parent (pam, X),parent (X, pat).
d) ?- parent (pam, X), parent (X, Y), parent (Y, jim).
2. Formulate in Prolog the following questions about the parent relation:
a) Who is Pat's parent?
b) Does Liz have a child?
c) Who is Pat's grandparent?

Me with this program in c++ ! computers represent color by combining sub-colors red, green, and blue (rgb). each sub-color's value can range from 0 to 255. thus (255, 0, 0) is bright red. (130, 0, 130) is a medium purple. (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (in other word, equal amounts of red, green, blue yield gray).given values for red, green, and blue, remove the gray part. ex: if the input is 130 50 130, the output is: 80 0 80. thus, find the smallest value, and then subtract it from all three values, thus removing the gray.
