HORRIBLE (from Spoj) has been solved.
Thank you.

Hi everyone!
A while ago I've decided to learn Aho-Corasick algorithm and found the following problem at spoj.com:
I've implemented Aho-Corasick algo and received CRASH. I think, it's a normal situation for such input size.
Now I'd like to know, is this problem solvable using Aho-Corasick or only suffix tree fits in given constraints?
Thanks.
Sup, guys!
Let's consider the following problem: we have a set of strings (initially empty) and must handle two types of queries:
That's all. Of course, time/memory consuming should be as low as possible. Now I don't have an idea better than "Okay, let's use Aho-Corasick algo and each time, when we face query 1, let's destroy our old automaton and create a new one from scratch".
Thanks for your help.
You are given a string (|S| <= 10^5) and have to find such substring that repeats one after another maximum number of times. Or, if there are some such substrings, you must choose the longest/shortest/lexicografically_something.
For example: for test bacacacb
answer is ac
.
How to solve it? Thanks!
Hi, guys!
Today I tried to learn Graham Scan algorithm, but failed :(
Can you help me to find a bug in this code, please? http://ideone.com/IXFfS9 Algorithm is simple, but I still can't understand, why I have WA4 in problem A here http://codeforces.com/gym/100173
Can't even to find a test that can crash my solution :(
Thanks a lot!
May somebody recommend some? Thanks.
