For every postfix expression there exists a corresponding and uniquely defined infix expression that evaluates to the same number. The converse is not true. The infix expression a + b + c can be represented as either abc++ or ab+c+ in postfix. The reason for the ambiguity is the lack of brackets in the infix expression.
If the infix expression were "fully bracketed" there would be no ambiguity.Thus (a + b) + c pairs with ab+c+ and a + (b + c) pairs with abc++.
Example: the "fully bracketed" version of an expression a + b*c/d is (a + ((b*c)/d)).
The program should do:
* Take an infix expression from the standard input
* The expression must consist of digits (for numbers), symbols '(' and ')', and operations ('+', '-', '*', '/')
The terms in the expression might or might not be separated by one or several spaces, e.g. ( (56 + 32)* (16 -7))
* Convert the expression into the postfix form
* Output the postfix form to the screen
* Evaluate the resulting postfix expression
* Output the result
