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

Stacks stl

@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. :)

sheteyash: 2016-12-19 10:38:51

ye AC kya hota hain???

use stacks period.

AC!!! in c++-->0.0sec
my first stack problem

yo AC in one GO

mhto: 2016-11-21 18:32:28

woohoo... AC in one go :D

Good Problem ! AC in 1 go . #ff0000. However there is no use of priority given over here.

the expression is surely a full bracket expression..
