for(int i=1;i<=n;i++)
{
int coin_no;
cin>>coin_no;

for(int x=1;x<=coin_no;x++)
{
int val;
cin>>val;
value=value+val;
}
diff=value%2 ...

adnan_iut -------thank u for reply. but i still get wrong answer. here is the code with corrected 0.000



#include<iostream>
#include<math.h>


using namespace std;


int main()

while(cin>>a>>b>>c)
{
if(cin.eof())
break;

if(a!=0 && b!=0 && c!=0)
