@lzy13915136909 说白了题给的不是x,y，而是病例与治好了的比，要你算x,y

@lzy13915136909 先把第二个循环删了 然后把a[1],b[1]改为a[0],b[0](忘了下标0了） 还有数组int改double 你完全不测样例吗（

by miffy_123 @ 2024-05-20 21:33:23

是否应该强转double

by miffy_123 @ 2024-05-20 21:36:11

我认为你应该把第二个循环删了，a[0]b[0]单独输入，然后第一个循环改为从一到N，在循环里与第0个比较

怎么感觉你越改越糟糕了 具体来说：

    int n,a[1005],b[1005];
    cin>>n;
    for(int i=0;i<n;i++)
        cin>>a[i]>>b[i];

改为

    int n,a[1005],b[1005];
    cin>>n;
    cin>>a[0]>>b[0];
    for(int i=1;i<=n;i++)
        cin>>a[i]>>b[i];

if(a[i]-b[i]>0.05)
    cout<<"better"<<endl;
    else
    {
        if(b[i]-a[i]>0.05)
            cout<<"worse"<<endl;
        else
            cout<<"same"<<endl;
    }

改为

int k=(double)b[0]/a[0];
if(((double)b[i]/a[i]-k)>0.05)
            cout<<"better"<<endl;
        else
        {
            if((k-(double)b[i]/a[i])>0.05)
                cout<<"worse"<<endl;
            else
                cout<<"same"<<endl;
        }

忘记说了，循环记得改成从1到N的

@lzy13915136909 会了就好，不要不懂装懂
