In an Italian village, a hungry mouse starts at vertex (\textrm{st}) on a given tree(^{\text{∗}}) with (n) vertices. Given a permutation (p) of length (n)(^{\text{†}}), there are (n) steps. For the (i)-th step: A tempting piece of Parmesan cheese appears at vertex (p_i). If the mouse is currently at vertex (p_i), it will stay there and enjoy the moment. Otherwise, it will move along the simple path to vertex (p_i) by one edge . Your task is to find such a permutation so that, after all (n) steps, the mouse inevitably arrives at vertex (\textrm{en}), where a trap awaits. Note that the mouse must arrive at (\textrm{en}) after all (n) steps, though it may pass through (\textrm{en}) earlier during the process. (^{\text{∗}})A tree is a connected graph without cycles. (^{\text{†}})A permutation of length (n) is an array consisting of (n) distinct integers from (1) to (n) in arbitrary order. For example, (2,3,1,5,4) is a permutation, but (1,2,2) is not a permutation ((2) appears twice in the array), and (1,3,4) is also not a permutation ((n=3) but there is (4) in the array). Each test contains multiple test cases. The first line contains the number of test cases (t) ((1 \le t \le 10^4)). The description of the test cases follows. The first line of each test case contains three integers (n), (\textrm{st}), and (\textrm{en}) ((1 \le n \le 10^5); (1 \le \textrm{st}, \textrm{en} \le n)) — the number of vertices of the tree, the starting vertex, and the trap vertex. Each of the next (n - 1) lines contains two integers (u) and (v) ((1 \le u, v \le n), (u \neq v)) — the indices of the vertices connected by an edge. It is guaranteed that the given edges form a tree. It is guaranteed that the sum of (n) over all test cases does not exceed (10^5). For each test case: If no such permutation exists, outp
