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+^*

Solved it using binary expression tree. Class Tree that has pointers to the left and right subtrees and two functions one fills the tree from the input string and the second one reads it in postfix traversal. |

In this case (a+(b+d)^k) is it abd+k^+ ? . Please correct me if I'm wrong |
