sorry @Subham2409 ,
you misunderstood the issue or for better says you have inserted a file with the algorithm,
but the algorithm is to be integrated in the framework, for precision, the algorithm has to be implemented in the Graph.hpp template file, as the other algorithm already present.

Thank you
