Hey Chinmay, in this problem you are supposed to print all the combinations in sorted order and for that you can take vector<vector<int> > or set<vector<int> >, which will store all the unique combinations in sorted order and then you can print them. So, store your output array (int* out) in vector<vector<int> > or set<vector<int> > and print that vector or set when all the combinations are computed.
