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 if we give it a path of size 100 * 1000 and all edges with the same color without any query)
