ONP - Transform the Expression

Transform the algebraic expression with brackets into RPN form (Reverse Polish Notation). Two-argument operators: +, -, *, /, ^ (priority from the lowest to the highest), brackets ( ). Operands: only letters: a,b,...,z. Assume that there is only one RPN form (no expressions like a*b*c).

Input

t [the number of expressions <= 100]
expression [length <= 400]
[other expressions]

Text grouped in [ ] does not appear in the input file.

Output

The expressions in RPN form, one per line.

Example

Input:
3
(a+(b*c))
((a+b)*(z+x))
((a+t)*((b+(a+c))^(c+d)))

Output:
abc*+
ab+zx+*
at+bac++cd+^*

Very weak test cases...I realized after 3 months that my solution was wrong.

Very weak testcases :/
Even a wrong code of mine was accepted.... xD xD xD

@sheeteyash AC means answer corrected, i.e., your solution is accepted :P
after too many wrong answers, and wastage of 1 day, finally got AC. :)

use stacks period.
