#include<stdio.h>

int main()

{

long long int i,T,n,a;

float b;

scanf("%lld",&T);

for(i=1; i<=T; i++){

scanf("%lld",&n);

b= ((((n*n)+1)*1.00)/2);
a=b*n;

printf(“Case %lld: %lld\n”,i,a);

}

}

What’s the problem with the code??? Showing Wrong Answer in the sample test case???Plz , help.,…

I think, The judge is going crazy here .In IDE the result comes 500000500,but in the judge, it becomes 500000512!!!

What is going on???

**Simplify your equation** and don’t use float.

It’s solvable without using any floating point number.

Maybe your IDE is smarter and handle many errors you code.
