### 11630 - Cyclic antimonotonic permutations

Hello. I have tried to solve the problem 11630 : Cyclic Antimonotonic Permutations, but I repeatedly got Wrong Answer. This problem is very easy to validate my outputs, so I can ensure that my solution is correct, but Online Judge gives WA again and again ! Validation requires Special Judge but mayb...

I think there is an another approach of this problem. Its complexity is surely O(NlgC), where C is the upper bound of input scores, or coordinate-value : 10^9 Although balanced binary search tree (or, RB Tree) is virtually the most simple solution to this problem, I think, but there may be an anothe...

How about think of Divide and Conquer? Divide a large rectangle into four smaller rectangles. Coordinates are lower than 10000, therefore at the worst cases time complexity is about O(10000 * 10000 * lg(10000) ). But this rarely happens. In fact, N is quite small (N ≤ 100), so it will fit in the tim...

I have an another question. I also know how hashing works, and how trie works, (and surely how BST or set-dictionary works, too), but in this situation how should I implement tries? |∑| = 26, i.e. the number of available letter is 26 ('a' through 'z'), and almost string's LENGTH is about 10, so brut...

That's enough. The constant 2 is not so important. If your implementation of this algorithms into source code is right, you will get accepted. But when you want to make it faster, you need some optimizations. The operation phi <- phi * (i - 1) / i takes 2 operations, one multiplication and one divis...
