#include<iostream>
using namespace std;
int main(void)
{
    int n;
    while(cin >> n)
    {
        int a[n],b[n],c[n];
        for(int i=0;i<n;i++)
            cin >> a[i] >> b[i] >> c[i];
        for(int i=0;i<n;i++)
        {
            if(a[i]<b[i]+c[i] && b[i]<c[i]+a[i] && c[i]<b[i]+a[i])
                if(a[i]==b[i] && b[i]==c[i])
                    cout << "Case " << i+1 << ": Equilateral" << endl;
                else if(a[i]==b[i] || b[i]==c[i] || a[i]==c[i])
                    cout << "Case " << i+1 << ": Isosceles" << endl;
                else
                    cout << "Case " << i+1 << ": Scalene" << endl;
            else
                cout << "Case " << i+1 << ": Invalid" << endl;
        }
    }
}

為什麼會這樣?請大家幫我解答一下

您的答案為: Case 5: Invalid 正確答案為: Case 5: Scalene 

大哥啊，你也太有梗了吧

你是想重現google 大神們都在哪下X片

是嗎？

怎麼沒有順便說錯在哪呢？
