## Ticket PuzzleProblem #210 |

Old tickets (perhaps from USSR times) with 6-digit numbers

When I travel over the city by public transport, I get the ticket which usually contains `6`

-digit number and start
trying to build an arithmetic expression from this number according to following rules:

- between any two digits one of the operators
`+`

,`-`

,`*`

,`/`

could be inserted - or these digits could be just "glued" together to form a larger value; - brackets could be added to provide correct operations priority;
- the expression should yield
`100`

as a result.

For example, yesterday it was number `151374`

which could be solved in several ways:

```
1 + (5 + 1 + 3) * (7 + 4) = 100
(1 * 5) + (13 * 7) + 4 = 100
```

If ever I could not come up with solution I wonder, whether it is really not possible or I am just not smart enough.
So let us write the program to help checking this out. We will try to solve this for different target values,
not necessarily for `100`

.

**Few restrictions:**
- let us agree that division could be used **only** if the first value is divisible by the second;
- please surround **every** binary operation by brackets to avoid priority issues (and help checking your expression) -
i.e. expression with `5`

operators should have `5`

opening and `5`

closing brackets;
- unary minus operation is not allowed, though intermediate results inside expression could be negative.

**Input data** will contain amount of test cases in the first line.

Next lines will contain test cases - the ticket number and the "target" value (separated by equals sign).

**Answer** should contain proposed expression for each test case. If there is no solution - output zero. Separate
answers with spaces (but do not use spaces inside expression).

Example:

```
input data:
5
151374=100
256128=128
577976=154
942511=175
767494=168
answer: (1+((5+1)+3)*(7+4)) (256-128) ((((5*7)*7)-97)+6) 0 (((7-6)*74)+94)
```
