csp-j T3我在洛谷上测的官方数据版是80分，但是ccf为什么只给60分? 这是源代码(认证时交的，洛谷上是把文件操作注释后交的):

#include <bits/stdc++.h>

int a[] = {6, 2, 5, 5, 4, 5, 6, 3, 7, 6};

__int128 dp[N], INF;
int T, n;
inline void print(__int128 x)
{
    if(!x) return;
    print(x / 10);
    putchar(x % 10 + '0');
}
int main()

    freopen("sticks.in", "r", stdin);
    freopen("sticks.out", "w", stdout)
    cin >> T;
    while(T--)
    {
        INF = 0;
        cin >> n;
        if(n != 1 && n % 7 == 1)

            cout << "-1\n";
        else
