back to boardTo admins: problem task in Russian and in English The problem task in Russian isn't equal to the problem task in English. The English text have following sentence: "You have to put the fence in the minimum number of squares so that the goat will be able to visit exactly K squares." It means that our region built could contain only K squares and something else, for example halves squares (as in example). But in the problem task in Russian this sentence is as follows: "Требуется, поставив минимальное число секций, предоставить козлу участок ровно из K квадратов." It means that the region contains only K squares and nothing else. I think that this sentence should be rewritten as follows: "Требуется, поставив минимальное число секций, предоставить козлу возможность посетить ровно K квадратов." And something else. English sentence contains phrase: "to put the fence in the minimum number of squares". But how should we count number of squares if the fence is put on the bound of two squares?!! Re: To admins: problem task in Russian and in English "You can build a fence in some of the garden's elementary squares." (English version) "Хозяева козла умеют ставить секции забора в отдельных элементарных квадратах на поле." (Russian version) So the fence consists of the unit squares, not of line segments. Sample test can be written as follows: ..X. .X.X X..X .XX. Edited by author 03.10.2009 17:22 |
