3. Give an efficient algorithm that takes as input a directed graph G - (V, E) with edges colored either blue or red and a starting vertex s and outputs ihc: list of all vertic where theris a path (noi sarily sixmple) thai goes from s to t and alternates between blue and red edges. (4 points for correct algorithm description, 3 for correctness proof, and 3 for efficiency and time analysis,)
