WebBreadth-first-search is the algorithm that will find shortest paths in an unweighted graph. There is a simple tweak to get from DFS to an algorithm that will find the shortest paths on an unweighted graph. Essentially, you replace the stack used by DFS with a queue. However, the resulting algorithm is no longer called DFS. WebImplement the depth-first search (DFS) algorithm. To make your algorithm complete, write the graph search version of DFS, which avoids expanding any already visited states. Your code should quickly find a solution for tinyMaze.txt (below)
