2. Suppose you are given a directed graph G = (V, E) and two vertices S and t. Describe and analyze an algorithm to determine if there is a walk in G from S to t (possibly repeating vertices and/or edges) whose length is divisible by 3. For example, given the graph shown below, with the indicated vertices s and t, your algorithm should return True, because the walk S > w > y > x > S > w > t has length 6. 63 6) it; Advice: Build a new graph to model your progress during a walk. For the vertices, describe some way to encode your current location in G along with a little more information to help you know how many steps (mod 3) you 've taken
