For this, first, we'll create a boolean array visited. Then, we'll walk through input string character by character and mark the character as visited. Please note that Uppercase and Lowercase are considered the same.

WebFeb 24, 2012 · a bool is defined as false: zero. true: not-zero. Depending on your compiler you may get some non-1 values in there because bool is not necessarily 1.

WebDFS(int v, boolean [] visited, String psf) is the recursive function that implements the DFS algorithm. It takes the current vertex v, a visited boolean array, and a psf string (which stands for "path so far") as input. It marks the current vertex as visited, adds it to the current path, and then recursively visits all unvisited neighbors of v.

WebApr 11, 2024 · However, graphs may contain cycles, so we may visit the same vertex again and again. To avoid that, we can use boolean visited array to mark the visited vertices. The above code traverses only the vertices reachable from a given source vertex. To do complete BFS traversal for disconnected graphs, we need to call BFS for every vertex.
WebJan 3, 2024 · We create 2 arrays : visited and distance, which record whether a vertex is visited and what is the minimum distance from the source vertex respectively.
