Circle Coloring

You are given three sequences: a1,a2,,ana_1, a_2, \ldots, a_n; b1,b2,,bnb_1, b_2, \ldots, b_n; c1,c2,,cnc_1, c_2, \ldots, c_n.

For each ii, aibia_i \neq b_i, aicia_i \neq c_i, bicib_i \neq c_i.

Find a sequence p1,p2,,pnp_1, p_2, \ldots, p_n, that satisfy the following conditions:

  • pi{ai,bi,ci}p_i \in \{a_i, b_i, c_i\}
  • pip(imodn)+1p_i \neq p_{(i \mod n) + 1}.

In other words, for each element, you need to choose one of the three possible values, such that no two adjacent elements (where we consider elements i,i+1i,i+1 adjacent for i<ni \lt n and also elements 11 and nn) will have equal value.

It can be proved that in the given constraints solution always exists. You don't need to minimize/maximize anything, you need to find any proper sequence.

Input

The first line of input contains one integer tt (1t1001 \leq t \leq 100): the number of test cases.

The first line of each test case contains one integer nn (3n1003 \leq n \leq 100): the number of elements in the given sequences.

The second line contains nn integers a1,a2,,ana_1, a_2, \ldots, a_n (1ai1001 \leq a_i \leq 100).

The third line contains nn integers b1,b2,,bnb_1, b_2, \ldots, b_n (1bi1001 \leq b_i \leq 100).

The fourth line contains nn integers c1,c2,,cnc_1, c_2, \ldots, c_n (1ci1001 \leq c_i \leq 100).

It is guaranteed that aibia_i \neq b_i, aicia_i \neq c_i, bicib_i \neq c_i for all ii.

Output

For each test case, print nn integers: p1,p2,,pnp_1, p_2, \ldots, p_n (pi{ai,bi,ci}p_i \in \{a_i, b_i, c_i\}, pipimodn+1p_i \neq p_{i \mod n + 1}).

If there are several solutions, you can print any.

Note

In the first test case p=[1,2,3]p = [1, 2, 3].

It is a correct answer, because:

  • p1=1=a1p_1 = 1 = a_1, p2=2=b2p_2 = 2 = b_2, p3=3=c3p_3 = 3 = c_3
  • p1p2p_1 \neq p_2, p2p3p_2 \neq p_3, p3p1p_3 \neq p_1

All possible correct answers to this test case are: [1,2,3][1, 2, 3], [1,3,2][1, 3, 2], [2,1,3][2, 1, 3], [2,3,1][2, 3, 1], [3,1,2][3, 1, 2], [3,2,1][3, 2, 1].

In the second test case p=[1,2,1,2]p = [1, 2, 1, 2].

In this sequence p1=a1p_1 = a_1, p2=a2p_2 = a_2, p3=a3p_3 = a_3, p4=a4p_4 = a_4. Also we can see, that no two adjacent elements of the sequence are equal.

In the third test case p=[1,3,4,3,2,4,2]p = [1, 3, 4, 3, 2, 4, 2].

In this sequence p1=a1p_1 = a_1, p2=a2p_2 = a_2, p3=b3p_3 = b_3, p4=b4p_4 = b_4, p5=b5p_5 = b_5, p6=c6p_6 = c_6, p7=c7p_7 = c_7. Also we can see, that no two adjacent elements of the sequence are equal.
