Giving compilation error in using inbuilt sorting
as far as the first error was concerned
the correction is this
but
it seems that the sort stl does not have overloaded function for sorting datatype
vector<pair<pair<int,int>>, int >
because even with simple call to sort u get an error
then how to apply sorting
make a custom class and then u can send the class object as parameter then write the custom sort function
maybe that will help
