    A Math problem for brain surgeons

    Give a function so X can be transformed to Y? Where;

    If X is 5; Y should be 4
    If X is 6; Y should be 3
    If X is 7; Y should be 2
    If X is 8; Y should be 1

    For example;
    You can say (Y = X-1) is such a formula. If we plug it in:

    5-1 = 4 (Correct)
    6-1 = 5 (Nop)
    7-1 = 6 (Nop)
    8-1 = 7 (Nop)

    So, is there a formula that will do this transformation?

    I came up with one but its too tedious. I am sure the brain surgeons of gupshup can do better!

    can you tell us if it is linear, quadratic, cubic, etc?

    unless you want people to make pure luck for a mathematical problem

      Easy Peasy...

      Y = 9 - X

      Okie so does that qualify me as a brain surgeon??? http://www3.pak.org/gupshup/smilies/tongue.gif

          LOL!

          Maddy you drained the suspense out of it! I was hoping a few more questions like hmcq. :-P

          You want to know what my computer science teacher came up with, when I asked him?

                As per my teacher;

                Code:
                if (X >= 5) && (X <= 9)
                Y = X - (((X mod% 5) << 1) - 1);
                Those who are not familiar with C code, here is the explaination:

                The method is to first x mod 5, then multply it by 2 and then subract 1 from it. And then subtract the result from original X. :-P

                Hehe! Correct but an overkill!

                It just proves that its not the question but how you ask it that matters. He was laughing like hmcq when I told him the simpler version. Phew! He wasn't mad.

                p.s: The modulus (mod), or remainder, divides number1 by number2 and returns only the remainder as result!
                I know that you believe that you understood what you think I said, but I am not sure you realize that what you heard is not what I meant.
