Leetcode 5345 by a vote of team rankings

A very simple data structures subject, the time of writing are not familiar with the stl card. . Mind blown up

Directly on the bar code:

 String rankTeams (Vector < String > & votes) { 
　　　　　// initialize a two-dimensional array to a certain space. . 
        Vector <Vector < int >> MP ( 27 , Vector < int > ( 27 , 0 ));
         int Len = votes.size ();
         int j_size votes = [ 0 ] .size ();
         for ( int I = 0 ; I <Len; I ++ ) 
        { 
            for ( int J = 0 ; J <j_size; J ++ ) 
            { 
                MP [votes [I] [J]- ' A ' ] [J] ++ ; 
　　　　　　　　　　// end coupled with the corresponding symbol, in addition to modifying the ordering rules may be modified corresponding to the key value of each 
                MP [votes [I] [J] - ' A ' ] [j_size ] = 26 is - (votes [I] [J] - ' A ' ); 
            } 
        } 

        String ANS = "" ; 
　　
        Sort (mp.begin (), mp.end (), Greater <Vector < int >> ()) ;
         for ( int I = 0 ; I <j_size; I ++ ) 
        { 
            ANS + = ( 26 is -mp [I] [j_size] +'A');
        }
        return ans;
       
    }
