Cypher

Luca has a cypher made up of a sequence of nn wheels, each with a digit aia_i written on it. On the ii-th wheel, he made bib_i moves. Each move is one of two types:

  • up move (denoted by U): it increases the ii-th digit by 11. After applying the up move on 99, it becomes 00.
  • down move (denoted by D): it decreases the ii-th digit by 11. After applying the down move on 00, it becomes 99.

Example for n=4n=4. The current sequence is 0 0 0 0.

Luca knows the final sequence of wheels and the moves for each wheel. Help him find the original sequence and crack the cypher.

Input

The first line contains a single integer tt (1t1001 \leq t \leq 100) — the number of test cases.

The first line of each test case contains a single integer nn (1n1001 \leq n \leq 100) — the number of wheels.

The second line contains nn integers aia_i (0ai90 \leq a_i \leq 9) — the digit shown on the ii-th wheel after all moves have been performed.

Then nn lines follow, the ii-th of which contains the integer bib_i (1bi101 \leq b_i \leq 10) and bib_i characters that are either U or D — the number of moves performed on the ii-th wheel, and the moves performed. U and D represent an up move and a down move respectively.

Output

For each test case, output nn space-separated digits  — the initial sequence of the cypher.

Note

In the first test case, we can prove that initial sequence was [2,1,1][2,1,1]. In that case, the following moves were performed:

  • On the first wheel: $2 \xrightarrow[\texttt{D}]{} 1 \xrightarrow[\texttt{D}]{} 0 \xrightarrow[\texttt{D}]{} 9$.
  • On the second wheel: $1 \xrightarrow[\texttt{U}]{} 2 \xrightarrow[\texttt{D}]{} 1 \xrightarrow[\texttt{U}]{} 2 \xrightarrow[\texttt{U}]{} 3$.
  • On the third wheel: $1 \xrightarrow[\texttt{D}]{} 0 \xrightarrow[\texttt{U}]{} 1$.

The final sequence was [9,3,1][9,3,1], which matches the input.
