Руины титанов: проходя сквозь стены 20 окт 2012 16:09 What if one of them is outside the trap? Do they still need to keep contact (have at least one common corner)?

Too bad it doesn't clarify anything about original question, so I'll answer it: yes, they have to be in adjacent rooms even after one of them got out.

Руины титанов: проходя сквозь стены 24 окт 2012 22:45 So the first one out must remain in contact with the other, but if the other can step out on the very next turn, and by stepping out they become separated, it's OK...? 2rf Re: When one of them is outside, do they need to keep contact? [3] // Задача 1912. Руины титанов: проходя сквозь стены 25 окт 2012 04:00 In my solution what you said is not allowed, but it seems like in optimal solution this situation can't happen.

Руины титанов: проходя сквозь стены 25 окт 2012 11:24 > In my solution what you said is not allowed Then shouldn't the answer to your example be 3 instead of 2 as your wrote? 1 up 1 right 2 right Your answer of 2 requires: 1 up 2 right But this separates them.

Руины титанов: проходя сквозь стены 25 окт 2012 16:26 Yes, but there are no walls outside the given rectangle, so while executing "1 right" command you don't pass through thin wall and thus the answer isn't increased ;D Bogatyr Re: When one of them is outside, do they need to keep contact? // Задача 1912. Руины титанов: проходя сквозь стены 25 окт 2012 18:27 Doh. Right you are. I did not read the problem statement properly. I was thinking it was "number of moves." Walker Re: When one of them is outside, do they need to keep contact? // Задача 1912. Руины титанов: проходя сквозь стены 25 авг 2021 12:02 I think yes.Because I got WA5 if no.But AC if yes. My English is very bad.Sorry. L0ve Small performance tip // Задача 1912. Руины титанов: проходя сквозь стены 28 авг 2018 20:44 Shortest path with respect to number of crossed walls is also shortest with respect to number of moves.

Is this test correct or I don't understand the statement? Vedernikoff 'Goryinyich' Sergey (HSE: АОП) 2 ADMINS: weak tests! [9] // Задача 1912. Руины титанов: проходя сквозь стены 4 янв 2013 00:49 Hi there, My AC code (and, I think, many others) outputs "-1" for the following test, whereas according to the problem statement right answer is "3": 1 5 +-+-+-+.+-+ | | .1|2| | +-+.+-+-+-+ It seems this problem needs more good tests.

[2] // Задача 1912. Руины титанов: проходя сквозь стены 17 янв 2013 17:32 Do you check this mailbox? Some time ago I sent new tests for 1005 to kill greedy sols - and no reaction on timus side. If you really need new tests for this problem and will add them - I can prepare. Erop [USU] Re: 2 ADMINS: weak tests! [1] // Задача 1912. Руины титанов: проходя сквозь стены 18 янв 2013 00:23 Some time ago limitations have been modified to 2 <= n, m (was 1 <= n, m). Sorry for misinformation.

Руины титанов: проходя сквозь стены 18 янв 2013 00:55 I think the problem could be more interesting and challenging with old limitations and new tests. Currently it is rather straightforward. tvhong Re: 2 ADMINS: weak tests! [2] // Задача 1912. Руины титанов: проходя сквозь стены 27 апр 2014 06:21 It should be "Death" for your test case as they need to "always" stay close together. Even when one of them is out.

According to the problem statement they need to stay close to each other only in order to keep moving. Here it is possible for both of them to leave the labyrinth. Bogatyr Re: 2 ADMINS: weak tests! // Задача 1912. Руины титанов: проходя сквозь стены 6 окт 2015 16:55 > You're wrong. According to the problem statement they need to stay close to each other only in order to keep moving. Your interpretation is not supported by the problem language. I agree with tvhong, the problem statement clearly says that they must stay close. If your interpretation was correct then the second sample would not be "Death." zzyzzy12 help me!!!

Руины титанов: проходя сквозь стены 24 окт 2012 22:42 The first may not go "up" out the top exit because according to the problem statement they must remain in rooms sharing walls/corners on every move. PetrSU #1: Fedulin, Ioffe, Filippov Пустые стены // Задача 1912. Руины титанов: проходя сквозь стены 20 окт 2012 14:37 Может ли между двумя соседними по стороне комнатами не быть пустоты (пробел)? то есть верно ли, что каждая комната всегда окружена какими-то стенами и углами?
