Problem description is well known for the degree that bears like numbers very much.

It recently in the study of primary arithmetic, the first time to find the world there are two-digit, three-digit number ... Even the number of n digits!

But this time the arithmetic question is not simple, because contains the expression Bomb the # number, the degree degree bears call arithmetic of Bomb.



The Bomb in Bomb number, which is the #, expands some numbers, which leads to the final unfolding of the numbers beyond what the bear can understand. For example, "(1) # (3)" means "1" appears 3 times, will be expanded to "111",

Similarly, "(12) # (2) 4 (2) # (3)" will be expanded to "12124222".

For ease of understanding, the BNF representation of bomb number is given below.

```
<bomb number>: = <bomb term> | <bomb number> <bomb term>
<bomb term>: = <number> | ' (' <number> ') ' # ' (' <non-zero-digit> ') '
<number>: = <digit> | <digit> <number>
<digit>: = ' 0 ' | ' 1 ' | ' 2 ' | ' 3 ' | ' 4 ' | ' 5 ' | ' 6 ' | ' 7 ' | ' 8 ' | ' 9 '
<non-zero-digit>: = ' 1 ' | ' 2 ' | ' 3 ' | ' 4 ' | ' 5 ' | ' 6 ' | ' 7 ' | ' 8 ' | ' 9 '
```

Expand all the # numbers in bomb number, as the numbers can be long and result in 1 000 000 007 modulo.

Input first behavior T, which represents the number of input data groups.

Each group of data contains one bomb Expression.


-1≤t≤100

-1≤length (Bomb number) ≤1000

Output results for each set of data export expressions, resulting in 1 000 000 007 modulo.

Sample Input

41 (1) # (3) (12) # (2) 4 (2) # (3) (12) # (5)

Sample Output
