4. LDIISIOEI" UlJKSU'a 5 algorithm: Initialization Same as MSTPrim, but also dene a set S which is the complement on Computing loop while Q is nonempty do u ( Extract-Min(Q) 3( S U{n} for each v EAdjlu] do Relax(u. v. w) For the directed graph indicated by the sketch on the next page, on exactly,i which iteration of the while loop is the shortest path distance from the top left vertex with the heavy:r line to the black vertex at location (5 , 2)? Assume that the sequence of arrows shown persists throughout all the Vertices. and that each horizontal edge weight is set to +2, each vertical edge weight is set to +3. and each diagonal edge has weight 0. Break ties for ExtractMin lexicographically. for example. (2, 3) would come before (2. 5), if both had the same distance from the source estimate. We are asking at which point the estimate for the distance is the true minimum distance. This is different from asking at which iteration is the black node extracted. Finally. um the algorithm presented in class! (10 points) C'. 0000 O 0 6 0 O O 0000 O 0000 O O O O O CO
