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+^*

I've been struggling like crazy to get rid of NZEC. I am almost certain that this code (http://ideone.com/********) deals appropriately with all possible statements that may throw exceptions. I think the memory constraint might be the issue here. Would appreciate any help. (Francky) => Kindly read the notes, and use forum for any help. Last edit: 2015-02-21 15:53:05 |

Fully parenthesized expression :),so no need to use infix to post fix conversion algorithm,it is simpler than that... |

is this is a test case : (a + b^c) or there will be parenthesis always i.e. ( a+ (b^c)) |

here +- got same priority and /* got same but higher than +-and( and ^ has highest priority ->must take case of case when stack is empty and you tring to get top or pop element ->no need to take care of case/problem with no () at all Last edit: 2015-01-14 20:11:46 |
