    Question Data Structures / prefix and postfix

    Hi...

    I'm having a few problems with the book that I have regarding prefix and postfix portion of data structures. I was wondering if anyone knew of a web site that might have a few examples that I could learn from.

    thanks
    Thanks,

    Maybe someone can tell me if I'm right or wrong:

    prob: Translate each of the following expressions from prefix to postfix:


    a) / + x y ! n (prefix)


    x y + / n ! (my answer in postfix)



    b) / + ! x y n (prefix)


    x y + / n ! (my answer in postfix)

    These are my results, I'm just looking to see if I am doing this right.
    Thanks,

    -Rick
