NYOJ Binary Conversion 244

16 hexadecimal simple operation time limit: 1000 MS | memory limit: 65535 KB difficulty: 1

Description

Now we will give you a hexadecimal addition and subtraction expression, which requires that the result of the expression be output in octal.

Input

Enter a positive integer T (0 <T <100000) in the first line)
Next there are T rows. Each line inputs a string s (length less than 15) which contains two numbers and a plus sign or a minus sign. The expression is valid and the number of all operations is less than 31 characters.

Output

Each expression outputs a row and outputs the result of an octal expression.

Sample Input

329+482318be+67844ae1-3d6c

Sample output

441141001026565
