Contradiction of constraints in problem 580D div 2
Hi Codeforces,
In problem "Kefa and Dishes" (580D div 2), statements said that: "It is guaranteed that there are no such pairs of indexes i and j (1 ≤ i < j ≤ k), that xi = xj and yi = yj."
But in the 5th test case:
7 4 3 2 6 13 5 7 1 9 6 1 15 2 5 3 6 4 8
It's easy to see that x1 = x3. Was this test case invalid?
