Is there any condition for a graph to have a circuit that is both eulerian and hamiltonian ??
I came across this problem on Uva online judge from NWERC regional semilive 2010
I have thought about a method where map<vector<pair<int,int>>,int> dp stores the best possible score Jan for the state vector<pair<int,int>>.... but i dont know how to proceed further and feel that the method is inefficient...
please help......
