注意9行 or 9列的表插不进去

题目理解难度远大于编程难度，逻辑很简单，copy了一下别人的代码，然后修改通过的。
大部分人没通过的关键在于：对于9行 or 9列的表，无论你插入几都是错的！

#include <iostream>
using namespace std;

int main() {
    int r, c, r1, c1, r2, c2, ri, ci, rt, ct;
    while (cin >> r >> c >> r1 >> c1 >> r2 >> c2 >> ri >> ci >> rt >> ct)
    {
        if (r>9 || c>9)
            cout << "-1" << endl;
        else
            cout << "0" << endl;

        if (r1 >= 0 && r1<r && c1 >= 0 && c1<c && r2 >= 0 && r2<r && c2 >= 0 && c2<c)
            cout << "0" << endl;
        else
            cout << "-1" << endl;

        if (ri >= 0 && ri<r && r<9)
            cout << "0" << endl;
        else
            cout << "-1" << endl;

        if (ci >= 0 && ci<c && c<9)
            cout << "0" << endl;
        else
            cout << "-1" << endl;

        if (rt >= 0 && rt<r && ct >= 0 && ct<c)
            cout << "0" << endl;
        else
            cout << "-1" << endl;
    }
    return 0;
}
