为什么这段代码在实践中可以得到正确结果，但是却会有wrong answer的宿命？
小弟第一次来，请各位伟人帮助！



#include <iostream>
#include <vector>
using namespace std;
const int p_cycle=23,e_cycle=28,i_cycle=33;
inline void calc(int p, int e, int i, int d)
{
	static int nth=0;
	nth++;
	p%=p_cycle;
	e%=e_cycle;
	i%=i_cycle;
	int first;
	for(int ne=1;ne<=p_cycle*i_cycle;ne++)
	for(int np=1;np<=e_cycle*i_cycle;np++)
	  if(e+ne*e_cycle==p+np*p_cycle)
		for(int ni=1;ni<=e_cycle*p_cycle;ni++)
		if(p+np*p_cycle==i+ni*i_cycle)
 		{first=p+np*p_cycle;break;}
	cout<<"Case "<<nth
        <<": the next triple peak occurs in "<<first-d
        <<" days.\n";
}
int main()
{
	int acount=0;
	int p,e,i,d;
	vector<int> data;
	while(1)
	{
		cin>>p>>e>>i>>d;
		if(p==-1&&e==-1&&i==-1&&d==-1)break;
		acount++;
		data.push_back(p);
		data.push_back(e);
		data.push_back(i);
		data.push_back(d);
	}
	int x;
	for (int n=0;n<acount;n++)
	{
		x=n<<2;
		calc(data[x],data[x+1],data[x+2],data[x+3]);
	}
	return 0;
}
