开始的问题代码,不能过,效率低

#include <iostream>

using namespace std;

int main()
{   int p,e,i,d,n=1;

    while(cin>>p>>e>>i>>d){
        if(p!=-1&&e!=-1&&i!=-1&&d!=-1){
        for(int k =21252;k>0;k--){
                        ;
                if((23-p+k)%23==0&&(28-e+k)%28==0&&(33-i+k)%33==0)
                cout<<"Case "<<n<<": the next triple peak occurs in "<<k-d<<" days."<<endl;

                }
                 n++;
    }
    else break;
    }

}

改正后:

#include <iostream>
using namespace std;

int main()
{   int p,e,i,d,n=1;

    while(cin>>p>>e>>i>>d){

        if(p==-1&&e==-1&&i==-1&&d==-1)
            break;

        for(int k =1;;k++) //不能从21252找,因为题目是给定天数的下一次同一天,虽然倒着找出来的不用break还恰巧限制了范围,其实题目给出的如果找到第一次是不会超的
            if((k-p)%23==0&&(k-e)%28==0&&(k-i)%33==0&&k>d){
                cout<<"Case "<<n++<<": the next triple peak occurs in "<<k-d<<" days."<<endl;
                break;
            }

    }
    return 0;
}

准哥代码:
    #include<iostream>  
    using namespace std;  
    int main()  
    {  
        int i,d,e,p,a,n=0;  
        while(cin>>d>>e>>p>>a)  
        {  
            ++n;  
            if(d==-1&&e==-1&&p==-1&&a==-1)  
                break;  
            for(i=1;;i++)  
                if((i-d)%23==0&&(i-e)%28==0&&(i-p)%33==0&&i>a)  
                    break;  
            cout<<"Case "<<n<<": "<<"the next triple peak occurs in "<<i-a<<" days."<<endl;  
        }  
        return 0;  
    }  
感觉准哥的爽快清凉些!
