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+^*

go for shunting yard algorithm , but watch some vedio on it also . Try to implement your own code , dont

The expression is always full brackets (If not, I wont get AC).

The description given in problem is very less, read about RPN before attempting.

Solvable with string although stack is easier.

test cases do not check for cases like a^b+c

Please only solve using stack if coding in java c or c++ , DO NOT TRY STRING AND STRINGBUFFERS made it more complicated.
