Answer the following about the worst-case analysis for the following graph algorithm: Input: G = (V, E): graph with n vertices and m edges Input: n, m: order and size of G, respectively 1 Algorithm: GraphMystery 2 q= Queue() 3 visited= Array(nm) 4 Initialize visited to false 5 Enqueue the ordered pair (vo, Vo) on q 6 visited|0,0]=1 7 while q not empty do (vi, uj) = q. Dequeue() 9for vz N(vi) do for vy E N(vj) do 10 if . visited|x,y] then q.Enqueue(vx, vy) visited[z, y] true 12 13 14 15 16 end 17 end 18 if all entries in visited are true then 19 20 else 21return false 22 end end end return true
