вернуться в форумIt is easy, just sort and one linear cycle 1. Sort it by endTime, if endTime equals another endTime then sort them by startTime. 2. Open one iteration from 2 to n, init just check that,  is endTime<starTime, if so then ans++; 3. print ans; endTime and startTimes is one array with unchanged same index...   Sorry for poor English
  Re: It is easy, just sort and one linear cycle I don't think sorting by startTime is necessary. I think we should reverse-sort by startTime.  |
