ACM problem set 10300 - Ecological Premium

Hello there.

Ecological premium is a very easy problem. Just you have to look at datatype. Consider following test case -

Input:-

1
10
99999 99999 99999
99999 99999 99999
99999 99999 99999
99999 99999 99999
99999 99999 99999
99999 99999 99999
99999 99999 99999
99999 99999 99999
99999 99999 99999
99999 99999 99999

Output:-
99998000010

And following table is showing all fundamental integer types of variables in C:

Keyword	Size	Range	Format Specifier
int	2	-32768 --> +32767	%d
long	4	-2,147,483,648 --> 2,147,438,647	%ld
long long	8	−9223372036854775807 --> +9223372036854775807	%lld
unsigned int	2	0 --> 65535	%u
unsigned long	4	0 --> 4,294,967,295	%lu
unsigned long long	8	0 --> 18446744073709551614	%llu

So carefully choice datatype.

Happy coding.
