WA#5 but AC now , you should change "int n" into "long long n" . Re: Test Todor Tsonkov 30 окт 2006 21:20 Yup, 10x pal, you saved me from reading again and again this task and to wonder where I was wrong :) WA on 5 Alexander Prokazyuk (TKTL) 2 ноя 2006 07:17 Who can find my mistake?
[code deleted]
it passes all my tests, but it can't pass 5
Edited by moderator 29.12.2006 09:16 This is my formula
for (int i = 0; i <= n; ++i)
res += (i + n) * (n - i + 1) / 2 + i * (n - i + 1); This one is mine:
n*-~n*-~-~n>>1
Have fun! Re: WA on 5 Mihran Hovsepyan <<RAU>><<1 kurs>> 8 ноя 2007 16:00 Re: Test Petromil Petkov 10 ноя 2006 01:00 Thanks for the advice. Could you tell me what brings this change? n=10000 fits in an int, doesn't it?
Ha! Got accepted only with __int64 and not with long long... my djgpp returns a compilation error on such a line... could anybody explain me what should that be?
