Below is the implementation of Depth's first search to count the no. of cycles with length n in an undirected graph using an adjacency List. This algorithm is also very important from the interview point of view. Suppose we have the below graph given, and we want to find no. of cycles...

To represent this graph in JavaScript, we can use an adjacency list: constgraph={A:['B','D'],B:['A','C','E'],C:['B'],D:['A','E'],E:['B','D','F'],F:['E'],}; Implementation ofBFSusing a queue to traverse the graph: ...

Using DFS tree, we can solve the problem without any advanced data structures. In the original problem, the graph need not be connected. However, observe that: if the graph has no non-bipartite connected components, then removing any edge will produce a bipartite graph; if the graph has ...
Let's take this graph. Here A is connected to E,B,D ; B is connected with A,D,C ; C is connected with B ; D is connected with A,B and E is connected with A ; F is not connected. We represent this graph using an Adjacency List. Here is the code (in Python) ...
