Hard (Challange) Problems

Hi.
I want to solve some good problems in DP, Geometry, Graph, BST, RB-Trees ... to improve my knowlage. Here is my statistic http://acm.uva.es/cgi-bin/OnlineJudge?AuthorInfo:61365 Please give me IDs' of such good problems.

THX.

P.S. Sorry for my bad English.

AC

I've got AC in 0.172 sec, I'd mistake in Tarjan's algorithm.

Cactus

I've written this problem, but I think my program is wrong. When I give this input it returns that given graph is cactus, but I think it isn't. Here is input: 1 4 5 0 1 1 2 2 1 2 3 3 0 Here edge 0 -> 1 is in two cycle (0 -> 1 -> 2 -> 3 -> 0 and 1 -> 2 -> 1). My algorithm is such: 1) Determine if the...

I found some articles were was written absolut center. I think it and only center are the same things. Center of Graph is point somewhere in the edge of graph from which the largest distance to verteces is minimum.

You're right about my signature ;).

Absolute Center of Graph.

I'm looking for eficient algorithm, which finds absolute center of graph. If u know this algorithm or some e-book in which it's described please post here.

Thanks.

TLE

ayon I used your algorithm and got TLE. Here is my code, if u find there any bug please post here: #include <stdio.h> #include <stdlib.h> #include <string.h> class node { public: char s [100]; int l, r, p, P; node () { l = r = -1, P = p = 0; s [0] = '\0'; } }; int root, m; char ch, s [100], f [100]...

P3498 - Stacking Cylinders (from North America 2006-06)

Hello. I think this problem is simple (if u know little geometry :wink: ), but it get's WA, than I saw in this problem's ranklist and nobody has solved it. Maybe there's some problem with judge system or something other. Here is my code and if u find bug post here plz: #include <stdio.h> #include <s...

WA.

Hi all. I wrote this program, but it gets WA. Now I looked Nikolay Archak's algorithm and its and my algorithms is same, but my code gets WA. PLZ help here is my code: Program permalex; Var I, J, K, N, Sol : LongInt; Ch : Char; S, SS : String; A : Array ['a' .. 'z'] Of LongInt; Function GCD (A, B : ...
