WebSep 26, 2016 · I have made an Adjacency list using and a linked list. Inside the struct for node, I have data, next and visited. When I try setting visited to true in the DFS function, The algorithm does not work correctly. It only works when I create a new array storing the boolean values and using that array for the dfs algorithm. WebMethod 2 : Create a DFS function which takes matrix, cell indices and direction. Now, we will check the cell indices pointing to a valid cell (that is, not visited and in bounds),if not, skip this cell. Print the value of the cell. And Mark matrix cell pointed by indicates as visited by changing it to a value not supported in the matrix.
