[SHAHADAT]

Hi,
I have got wa 10070.Please give me critical input output.

[ayon]

didn't you read this topic?
http://online-judge.uva.es/board/viewto ... ight=10070
use "search" button, that'll help you, and for 10070 you must use bigNum.

[emotional blind]

bigNum is not necessery,
There is number theory.

thats right, this problem can be solved using only number theory, i meant that the input year must be taken as bigNum, not as int or long long

Thanks a lot all of you.
I got it accepted....................

hi,
i m getting wa in the 10070 for several times. i did some corrections bt still it is WA.
Any1 there 2 help me, plz?

hello-

I don't think you are handling the leap year property correctly..

A line from the problem statement..
A year that is divisible by 4 and not divisible by 100 with the exception that years that are divisible by 400 are also leap year.

it means:
if( year % 400 == 0 ) leap_year;
else if( year % 100 == 0 ) not_leap_year;
else if( year % 4 == 0 ) leap_year;
else not_leap_year.

so, the year 2404 is a leap_year... but your code seems to think otherwise.

# And there are several other threads related to this topic. You should posted a reply on those, rather than opening a new thread..

Hope it helps..
