Victor Barinov (TNU) Test 12 [17] // Задача 1074. Очень короткая задача 3 авг 2006 16:47

Please check the 12-th test. I and others thinks that our solutions are correct, but they are WA on 12...

Maybe anyone can give a little hint?

Vladimir Yakovlev (USU) Your solution is definitely wrong [2] // Задача 1074. Очень короткая задача 3 авг 2006 17:30

Thank you! :)
But it is not helped me. Maybe you give me this test? Or any similar?

Vladimir Yakovlev (USU) No, try to think (-) // Задача 1074. Очень короткая задача 3 авг 2006 20:28

Krayev Alexey (PSU) Test 12 [10] // Задача 1074. Очень короткая задача 3 авг 2006 22:15

Yeah, I have WA12 too. I doubt if the test is really correct.
And one more question: what means pluses and minuses in brackets? (Sorry for offtop).

Krayev Alexey (PSU) Strange test [6] // Задача 1074. Очень короткая задача 4 авг 2006 01:37

It seems that 12 test has cases like
1e14234320000000
2
Is that output would be correct for this case:
1.00e14234320000000

12 test has cases like
1e-14234320000000
2
and correct answer for this case:
0.00

From my code:
if( exp > 1000 ) ... // make Output Limit
The result is Output Limit, test 12! So, exp is more than 1000 :)

From problem statement:
"It is guaranteed that a length of a result will not exceed 200 symbols."
Is it right (with such big exp and number != 0)?

Krayev Alexey (PSU) Re: Strange test [3] // Задача 1074. Очень короткая задача 4 авг 2006 20:24

No, that was bug in my check code. Later I submited smth like that:
if (e>1000 && !isnull(mantissa)) while (1);
and this code didn't cause tle.

KAV Re: Strange test [2] // Задача 1074. Очень короткая задача 4 авг 2006 20:35

I had the code:
if( abs( exp ) > 1000 ) ...   // the answer is 0.0000...
It got WA 12.

Then I decided to divide it into two parts: exp>1000 and exp<-1000.
if( exp < -1000 )
       ...   // 0.000... - 100%, yes?
else if( exp > 1000 )
{
    // I amn't sure that there can be such a situation, that's why I do only output limit
   while( 1 ) cout << "111\n";
}
Output Limit 12!

"It is guaranteed the the length of output would be less than 200 symbols".
I think, exp>1000 can be only when the number is 0 ( 0e10000 ). But then the right answer is 0.000 - the first code, which gets WA.

So, there is a test in 12th test where exp>1000 and number is NOT 0!

You forget that input file may contain a number of test cases. Maybe cases with big (and small) exponent your program processes correctly, but fails at other cases.
Although i agree that it is very, very strange.

Vladimir Yakovlev (USU) This multitest contains about 100 cases (-) // Задача 1074. Очень короткая задача 4 авг 2006 21:29

I)iver Re: Test 12(+) [2] // Задача 1074. Очень короткая задача 10 авг 2006 19:44

There are tests like
1e+00000000000000001
5
or
1e-10000000000000000
2

First, my program had WA on test 12. Than I fixed my bug with this tests, and finally got AC=)

Krayev Alexey (PSU) Re: Test 12(+) [1] // Задача 1074. Очень короткая задача 10 авг 2006 21:43

my program processes correctly these cases,
outputing:
10.00000
0.00

but still wa#12

Olympic Bear (Nikolay Dubchuk) Re: Test 12(+) // Задача 1074. Очень короткая задача 23 авг 2016 18:24

Try this test:
1+10
0
#

it's not a correct float number
