我测过数据都正确的,提交都是WA,麻烦高手看下!
#include<iostream>
using namespace std;

int main()
{
    int p,e,i,d,j,k=1;
    cin>>p>>e>>i>>d;
    while(!(p==-1&&e==-1&&i==-1&&d==-1))
    {
         p%=23;
         e%=28;
         i%=33;
         for(j=1;;j++)
         if((23*j+p-e)%28==0&&(23*j+p-i)%33==0)
         break;
         cout<<"Case "<<k++<<": the next triple peak occurs in "
         <<23*j+p-d<<" days."<<endl;
         cin>>p>>e>>i>>d;
    }

    return 0;
}
