Re: WA #5 Yermakov Alex <ONPU> 2 May 2010 01:58
Combined in this test must be 221... because 00:10 gives 1 minute , 00:59 give 1 minute , 05:00 gives 5, 01:01 gives 2...or... 01:01 gives 1 minute or 2 minutes ??
Re: WA #5 Sergey Lazarev (MSU Tashkent) 2 May 2010 11:31
00:10 - 1 minute;
00:59 - 1 minute;
05:00 - 5 minutes;
01:01 - 2 minutes.
All time is 9 minutes.

In this test you are allowed to talk up to 10 minutes per month for free. You talked only 9. So you should pay only monthly fee - 220.

Yes , thanks . I should write
[ else com=0 ]
after
 [ if(com > t){...} ]
