This story is about a boy, called Gena. He is quite a usual boy who goes to school, celebrates All Hallows Eve, also known as Halloween Day, and besides likes programming contests.

One Halloween Day he went from house to house begging for "soul cakes". He happened to collect many "soul cakes" of various tastes that day, and his happiness seemed have no limits. But his elder brother Roma, who was lazy and rude boy, demanded to give him ten cakes. Gena didn't loose control over the situation and gave his brother ten cakes of the same taste in order not to show that he had many tastes, because Roma could demand more cakes. Since that time Gena was thinking about that situation. And after Gena had learnt on Geometry classes about three-dimentional space figures, he invented the following problem.

Consider non-convex figure denoted as "corner" in three-dimentional space. It consists of four equal cubes. One of the cubes has a common face with each of the others. There is the only one point belonging to all four cubes, and this point coinsides one vertex of any cubes (see picture below). Every "corner" is charaterized by two values: color and an integer length of an edge of any cubes (denoted as "size"). "Size" is always equal to some power of two, so only index is given. The problem is to construct a big "corner" comprising given figures under the restiction of using as little number of different colors as possible given "size" of this big "corner".
