Determine the type of functional dependency
Consider Relation R (A, B, C, D, E, F) { AB>C C>B D>C E>D F>E } C.key=AF I have 2 questions 1) Isn't AB>C fully functionally dependent? Because the definition of full functional dependency ... AB can determine C,which is the case here. 2) Does F>E exhibit partial dependency? How do I determine if its partially dependent?

Is array implementation better or the min heap in case of Prims algorithm
For prim's algorithm array implementation takes $O(V^2)$ while min heap implementation takes $O((E+V)\log V)$ time. For dense graph $E = O(V^2).$ So is array implementation considered better or the min heap one??? Does the min heap implementation run better for graph with less edges??
