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 ab*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. Example
