ONP  Transform the Expression
Transform the algebraic expression with brackets into RPN form (Reverse Polish Notation). Twoargument 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+^*

if don't know stacks you can use vector but stack makes your life easier. But while using any data structure be aware of the string and char difference and make it a point.

@lazorzor. There are multiple test cases. You need to read the number of testcases, and process each one.

If you are really stuck search in google "shuting yard algorithm" there are an implementation in pseudocode.

Browse wikipedia for RPN. You'll get an idea!
