I think the test data has some problem.
I didn't print anything and got an AC.
Please take a look on this.

In problem statement there is just a line about specification
"Look at the samples below for the exact format."

And I think the sample output is not clear even lead to PE

First, I cannot tell from the sample output whether I should print a blank line
"after" each test case
or
"between" each test ...

in the sigma summation, it should be
sigma(k=start to end) rather than
sigma(k=a+start to a+end)

It seems that the times of submitted in older problems is not right
I saw my old submissions in problem 100 at http://acm.uva.es/p/statusjudge.php?h=3 ... 16&u=53469
and it seems at least 8
but on the author statistics it counts 4

http://online-judge.uva.es/p/problemsta ... p?prob=997 is the problem statistics of 997
and the solve rate is 125%
ac is 4, and "Number of users who solved" is 5
