Petersen Graph

The following graph G is called a Petersen graph and its vertices have been numbered from 0 to 9. Some letters have also been assigned to vertices of G, as can be seen from the following picture:
Let's consider a walk W in graph G, which consists of L vertices W_{1}, W_{2}, ..., W_{L}, such that W_{i} is connected with W_{i + 1} for 1 ≤ i < L. A string S of L letters 'A''E' is realized by walk W if the sequence of letters written along W is equal to S. Vertices can be visited multiple times while walking along W.
For example, S = 'ABBECCD' is realized by W = (0, 1, 6, 9, 7, 2, 3).
Your task is to determine whether there is a walk W which realizes a given string S in graph G, and if so, find the lexicographically least such walk.
Input
The first line of the input contains one integer T denoting the number of testcases to process.
The only line of each testcase contains one string S. It is guaranteed that S only consists of symbols 'A''E'.
Output
The output should contain exactly T lines, one line per each testcase in the order of their appearance. For each testcase, if there is no walk W which realizes S, then output 1. Otherwise, you should output the least lexicographical walk W which realizes S. Since all of the vertices are numbered from 0 to 9, then it can be encoded as a string consisting of symbols '0''9' (see the "Examples" section for more details).
Constraints
1 ≤ T ≤ 8;
1 ≤ S ≤ 100000(10^{5}).
