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).


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

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


The expressions in RPN form, one per line.

AC in one go, took 0.07 sec!!
Where to see test cases of problems?? Anyone knows??

Not enough tricky cases.

Accepted in one go , 0.00 in cpp 14 , it's just a direct implementation of Shunting yard algorithm ( from infix to postfix).

AC in one go,also take 0.00 sec
