(c) i. What is the advantage of using Karnaugh map (K-map)? ii. Fill in the following K-map for the Boolean function F(x, y, z) = p.y.z + .y.z+x.y.z+x.y.z 00 01 11 10 N 0 1 iii. Use the previous K-map and find a minimisation, as the sum of three terms, of the expression F(x, y, z) = r.y.z+m.y.Z+x.y.z + x.y.z
