Справка в НацОС | 13 май 2020 15:22 | 4 | Does anybody know what is so special about test no 29? I am positive that my solution is correct (which is obviously not the case) but it gets WA 29. I even compared it with a slow solution (BFS) but I did not find any differences. Please, I would really appreciate some help because I have tested all possible input combination for length 8 and the slow and fast solution produce the same answers.
I FOUND MY MISTAKE :)

Есть 111, нажатием на F1 111 превратится в 011. Затем, находясь на первой справа открытой вкладке( 2 позиция ), закроем следующую, то есть 011 --- 010. Затем F1 --- откроем 1 вкладку (110). После через 1 вкладку закроем следующую ( 110 --- 100 ). Далее F1 и все закрыто. 5 нажатий. Тест из примера

I don't know what's wrong but the 3-d test fails my program with "Wrong answer". Well, I have checked it manually and everything is OK, answers are right. Is this a problem with your checking system? What you mean by "from 1 page to 2"??
What you mean by "from 1 page to 2"?? I mean the second page's opening from first page. the second page is already opened!
1) press F1 - we close the first page. Now we are on the second page [1]11 -> 0[1]1
2) close third page 0[1]1 -> 0[1]0
3) F1 - open first page. Now we are on first page 0[1]0 -> [1]10
4) close second page [1]10 -> [1]00
5) F1 - close first page [1]00 -> 000
Nikita++ is absolutely right When we start from 101 layout - the page 2 is closed. We have to open page 2 to move to this page and than press the button for page 3 closing what's happened when we press "open next page" button? Page'll opened and we move to this page, or what? what's happened when we press "open next page" button? Page'll opened and we move to this page, or what? No. Page will openend. We don't move anywere. The current page won't be closed and we always are on the first opened page. Если есть вопросы, то пишите Test

We have 3 open windows = 111,so we press F1 and 111 --- 011. Then, when we are on the first opened window ( 2 position ), we can close the next: 011 --- 010. Then press F1 --- open 1 window (110). We are on 1 position and close 2nd ( 110 --- 100 ). Then press F1 and all is closed. We have pressed the buttons 5 times.

Can a page be opened more than once? Why can't we press F1 three times and close the pages?
