WebFinal answer. Transcribed image text: Program Requirements Design an algorithm using depth-first search (DFS) to determine whether an input graph is 2-colorable. A graph is called 2-colorable (or bipartite) if all its vertices can be colored using two different colors such that every edge has its two endpoints colored in different colors. For ... WebDFS is a uniformed algorithm that results in non-optimal solutions, and the DFS algorithm works as follows: Step 1: Start with the root node of any given graph or tree. Step 2: Now considering the root node as the first node of the graph and place this node at the top of the stack or list. Step 3: Now look for adjacent nodes of the root node ...
