Thankful in advance. Samsonov Alex [USU] Re: Hint about test 12 [10] // Задача 1074. Очень короткая задача 27 фев 2007 23:09 Oh, god :) I should better write it here. The thing is that if you use scanf("%d\n", &N); it reads not only number N and line break but also all whitespace characters after this linebreak. So, for example, it is possible that your program fails here: //some number 3 _1.e6//Space at the beginning of the line 3 It can say that ' 1.e6' is a correct number.

Очень короткая задача 28 фев 2007 00:55 Thanks a lot, but this situation is correctly processed in my program. But I have another question. Is number "1.e6" correct ? I'm talking about it's fractional part. According to problem's notation there shouldn't be numbers with decimal point and without fractional part. What can you say about this? Samsonov Alex [USU] Re: Hint about test 12 [4] // Задача 1074. Очень короткая задача 28 фев 2007 18:34 Yes, it's incorrect indeed. My bug :) Eng1neer Re: Hint about test 12 [3] // Задача 1074.

Очень короткая задача 23 окт 2008 08:40 Maybe someone has already written about it, but I didn't find. !!--BE CAREFUL:--!! Test 12 is correct, it has big exponent part like 2E100000000000 10 and answer would look like 0.00..000 Akaishuichi Re: Hint about test 12 // Задача 1074. Очень короткая задача 20 май 2009 21:32 the right answer should be 2<many zeros>.<10 zeros> but as it's granted that the output will not exceed 200 symbols, i don't think there will happen to be such inputs. or the maximum output can be a too long to deal with. >>Posted by SkorKNURE October 23, 2008 08:40 >> >>Maybe someone has already written about it, but I didn't >>find. >> >>!!--BE CAREFUL:--!! >> >>Test 12 is correct, it has big exponent part like >>2E100000000000 >>10 >> >>and answer would look like >>0.00..000 Edited by author 20.05.2009 21:33 sich_off (ONPU) Re: Hint about test 12 // Задача 1074.
