Test #14 wrong: Any idea why? mashennik 23 May 2012 20:21

Can anybody tell me what is wrong with my code:

var n,k: word;
begin
readln(n,k);
if n > k then
write( (n mod k) + 2*(n div k) )
else write(2);
end.

I couldn't find any test that my code gives wrong answer.

Mistake is here.

if n > k then
write( (n mod k) + 2*n div k )
Multiplication should be before dividing.

My solution shows 3. And it is a right answer.

Oh, your code has one more mistake.

if n mod k <> 0 , then you should add 1 to answer, not n mod k.
