To the problem setter: thanks for wasting an hour of time. If you want to make up some function then don't call it factorial, as it's really confusing to those of us who know that factorial is only defined for 0+.

[cpp]
// Accepted

#include <iostream>
#include <cmath>
using namespace std;

int refreshPos(double dimX, double dimY, double x, double y, char InitialPos){
double half_dimX=dimX/2;
double half_dimY=dimY/2;
if(x<half_dimX && y<half_dimY && InitialPos=='T')
return 1;
if(x>half_dimX && y<half_dimY ...

As far as I can tell the following two programs are producing the exact same output, however one is accepted while the other one is WA. How can this be? I'm really at a loss as to why this is the case.

You are missing a colon in the first print statement. That fixes it. Check the requirements.

I can't tell why with my test cases but the judge gives "WA" for my solution. Can you give me a case where my program gives the wrong answer? What am I missing here?

had to think about the problem more.

I can't figure out what was wrong with my submission, but the judge gives "Wrong Answer". Frustrated and suspicious that the judge was broken I found a solution posted for the 1998 European Contest (C - the exact same question). The judge gave a "Wrong Answer" for that as well.

My solution works for exponents up to 1024 (the max long double). I am getting "Wrong Answer". Is it because I need to check exponents higher then that? At what point should you stop? The question doesn't say.

Maybe there is some forumla rather then a brute force method that will give you an ...
