mysql - How can I filter a table with duplicate entries to display the rows that exist the most? -

-

i hope question makes sense.. have table called genre_tags contains music_id , genre_id column

it can contain duplicate entries 

music_id | genre_id 281           3 281           3 281           4 243           7 90            6 90            6 90            10

what want retrieve duplicate entries based on genre_id

so based on example above left result

music_id | genre_id 281        3 243        7 90         6

try this,

select  music_id, genre_id    tablename group   music_id, genre_id having  count(*) = (select count(*) total                         tablename b                     a.music_id = b.music_id                     group   music_id, genre_id                     order total desc                     limit 1)

c++ - Function signature as a function template parameter -

i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...
