🚖 Ranking

  • Submition rank Submition are ranked according to time and problem rank so the ranking equation is :-
                                                     Tstart - Tsub
       submition_rank =   problem_rank    -    _________________________    -    (    wrongAnswerCount   *   5    )

       Minimum Submmition Rank is = 40% Of problem rank
  • User rank
