B"There are n cities in Berland. Each city has its index -- an integer number from 1 to n. The capital has index r1. All the roads in Berland are two-way. The road system is such that there is exactly one path from the capital to each city, i.e. the road map looks like a tree. In Berland's chronicles the road map is kept in the following way: for each city i, different from the capital, there is kept number pi -- index of the last city on the way from the capital to i. Once the king of Berland Berl XXXIV decided to move the capital from city r1 to city r2. Naturally, after this the old representation of the road map in Berland's chronicles became incorrect. Please, help the king find out a new representation of the road map in the way described above. The first line contains three space-separated integers n, r1, r2 (2 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x895 xc2 xb7104, xe2 x80 x891 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89r1 xe2 x80 x89 xe2 x89 xa0 xe2 x80 x89r2 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n) -- amount of cities in Berland, index of the old capital and index of the new one, correspondingly. The following line contains n xe2 x80 x89- xe2 x80 x891 space-separated integers -- the old representation of the road map. For each city, apart from r1, there is given integer pi -- index of the last city on the way from the capital to city i. All the cities are described in order of increasing indexes. Output n xe2 x80 x89- xe2 x80 x891 numbers -- new representation of the road map in the same format."...
