Interpreter of Arithmetic Expressions

Implement an interpreter of arithmetic expressions. These expressions contain +, -, *, / operators (with common priorities and left associativity) and parentheses.

To simplify the task, consider we have only binary operators. There are no unary operators in our language.

Input specification

The first line of the input contains a number N. It defines the number of expressions your program should evaluate. These expressions are on next N lines. Each line contains exactly one expression.

Output specification

For each expression write one line containing the result – the computed value of the expression.

Example

• Input

2
2 * (3+5)
15 - 2**7

• Output

16
