use s > 3*n instead of s / 3 > n

Le Do Hoang Nam Re: WA 11 [4] // Problem 1688. Team.GOV! 28 Feb 2009 15:48

because s can be greater than max(long long). Use int64 instead.

fR0D Re: WA 11 [3] // Problem 1688. Team.GOV! 28 Feb 2009 16:03

But the maximum value of s can be 3000*2*10^6 which is well within the range of long long?

I use int64 and s>n*3 but have WA10, what's wrong with this program?

maybe you should use qword instead of int64 as i did? do not forget to make them both qword and multiply first by three rather than dividing another one.

Artem Fast Re: WA 11 // Problem 1688. Team.GOV! 11 Feb 2012 20:05

u can use unsigned long long and get AC

an100000 Re: WA 11 [2] // Problem 1688. Team.GOV! 28 Feb 2009 15:13

But if i use it i have wa 10
