weak test data or weak algorithm analysis?

Правка en5, от NikaraBika, 2015-12-02 08:56:26

Hello :)
This(14612490) is a brute force solution for 506D - Цветной граф мистера Китаюта and it's time complexity is absolutely O(n^2). (n <= 100 * 1000)
I submitted it and got AC!
Could someone help me? Why did it happen? Weak test data or fast servers?
(That code must get TLE in this test case(a path of size 100 * 1000 and all edges with the same color without any query))
