Problem Description
[center][img]../../../data/images/C531-1001-1.png[/img][/center] As a unicorn, the ability of using magic is the distinguishing feature among other kind of pony. Being familiar with composition and decomposition is the fundamental course for a young unicorn. Twilight Sparkle is interested in the decomposition of permutations. A permutation of a set S = {1, 2, ..., n} is a bijection from S to itself. In the great magician 〞〞 Cauchy's two-line notation, one lists the elements of set S in the first row, and then for each element, writes its image under the permutation below it in the second row. For instance, a permutation of set {1, 2, 3, 4, 5} 考 can be written as: \[\sigma = \begin{pmatrix} 1 & 2 & 3 & 4 & 5\\ 2 & 5 & 4 & 3 & 1 \end{pmatrix}\] Here 考(1) = 2, 考(2) = 5, 考(3) = 4, 考(4) = 3, and 考(5) = 1. Twilight Sparkle is going to decompose the permutation into some disjoint cycles. For instance, the above permutation can be rewritten as: \[\begin{pmatrix} 1 & 2 & 3 & 4 & 5\\ 2 & 5 & 4 & 3 & 1 \end{pmatrix} = (1 \quad 2 \quad 5) (3 \quad 4)\] Help Twilight Sparkle find the [b]lexicographic smallest solution. (Only considering numbers).[/b]
Input
Input contains multiple test cases (less than 10). For each test case, the first line contains one number n (1\(\leq\)n\(\leq\)\(10^5\)). The second line contains n numbers which the i-th of them(start from 1) is 考(i).
Output
For each case, output the corresponding result.
